Prior to this change, any inserted `<style>` nodes into shadow dom trees would be retained
in memory, even after the shadow dom tree has been removed. This commit fixes the memory
leak by tracking the inserted `<style>` nodes per host element, such that removal of the
host element also releases the style nodes.

It is important to use the correct major version of the Angular CLI when
following the examples in the tutorials. This commit provides a custom
element that renders an appropriate dist-tag in the setup step of
the tutorial when the docs are not in "stable" mode.

When aio yarn docs-only command runs on v12.14.1 it fails details given on issue #41979. Upgrading node version to v12.17.0 solves this but creates a new warning (node:467072) ExperimentalWarning: The ESM module loader is experimental.
This warning gets removed in v12.20.0. Upgrading node version to 12.20.0

The JIT compiler has a mapping from component to the owning NgModule
and tracks whether a certain NgModule class has been verified; these
maps causes any JIT compiled component and NgModule to be retained even
if they are no longer referenced from anywhere else. This commit
switches the maps to `WeakMap` to allow garbage collecting any
components and NgModules that are no longer referenced elsewhere.

Now that there is no need to work around the source-map bug in TypeScript
(https://github.com/Microsoft/TypeScript/issues/29300) we can just use
`resolvedTemplateUrl` for the source-map URL, rather than having a separate
property.

Such injectables were not appearing in the providers lists of their NgModule.
This commit updates the doc-gen to support associating these automatically.
Further, it also allows developers to mark other injectables that are provided
in an NgModule with a reference to the NgModule where they are provided.
The commit also does a refactoring of the `processNgModuleDocs` dgeni
processor code, to make it easier to maintain.

Indirect templates are templates produced by a non-literal expression value
of the `template` field in `@Component`. The compiler can statically
determine the template string, but there is not guaranteed to be a physical
file which contains the bytes of the template string. For example, the
template string may be computed by a concatenation expression: 'a' + 'b'.
Previously, the compiler would use the TS file path as the source map path
for indirect templates. This is incorrect, however, and breaks source
mapping for such templates, since the offsets within the template string do
not correspond to bytes of the TS file.
This commit returns the compiler to its old behavior for indirect templates,
which is to use `''` as the source map URL for such templates.

Currently if a PR modifies any file that configures a Github action
(e.g. a workflow file), the caretaker might face an error when merging
such PR:
```
! [remote rejected] merge_pr_target_11.2.x -> 11.2.x (refusing to allow a Personal Access Token to create or update workflow
```
This happens because Github requires the token being used for the
push operation to have the `workflow` scope set. This is a special
scope added by Github to ensure that no changes can be made on
upstream branches that might expose the `GITHUB_TOKEN` environment
variable, which is available for push builds and could cause the
token being leaked.
With this commit we enforce that the caretaker adds the workflow
scope to their github token. Since PRs can only be merged if reviewed
thoroughly, it's acceptable to allow workflow file changes being
merged through the merge tool by the caretaker (especially since we
also allow CircleCI config files being merged with the default
`repo`/`public_repo` scope).

After the changes to the `lang-none` styling in #41335, code snippets marked with
```
language="none" class="code-shell"
```
were being styled with the same foreground and background colours.
It turns out that most of these ought to be marked `language="sh"`
in which case the `code-shell` style became redundant and has been
removed.

Previously by default GitClient would log the commands it was executing at the
INFO level. This change moves the default level of this logging to DEBUG, while
still allowing callers of the methods to set the log level back to INFO.

Enable a GitHub action that implements our new feature request
[process](https://github.com/angular/angular/blob/ce8e011a9f7c6bac94292d632b0cc8822f710a66/docs/GITHUB_PROCESS.md#feature-request-process).
As a prerequisite, we need to create the following labels:
- `in backlog`
- `votes required`
- `under consideration`
- `insufficient votes`
The bot will also use the existing `feature` label to identify feature
requests.
With its current configuration, we need to kick the process off
manually. We currently also have a limit, meaning the bot will process
only 50 feature requests before it exits. Additionally, now the bot will
not close issues, it'll just comment on them and if they have an
insufficient number of votes, the bot will label them with `insufficient
votes`.
On the next iteration, we can:
- Expand the limit from 50 to infinity (removing the option from the
yml file)
- Set a cron configuration to kick off the bot automatically
- Enable autoclose by setting the `close-when-no-sufficient-votes` to
`true`

This commit adds support for skipping formatting in `<aio-code>`
elements (which are used by `<code-example>` and `<code-pane>` elements
under the hood) by specifying the `language` option as `'root'`.
This is useful for code-snippets that include plain text.

Currently the compiler treats `@page` rules in the same way as `@media`, however that is incorrect and it results in invalid CSS, because `@page` allows style declarations at the root (e.g. `@page (margin: 50%) {}`) and it only allows a limited set of at-rules to be nested into it. Given these restrictions, we can't really encapsulate the styles since they apply at the document level when the user tries to print.
These changes make it so that `@page` rules are preserved so that we don't break the user's CSS.

Content projection is an important part of Angular. However, it has
never been documented in the Angular documentation set. This topic
attempts to provide the basics of content projection for developers. It
is not a comprehensive guide; rather, it is a starting point that we
can hopefully expand upon in the future.
