Aurora Scharff 2cc99c73b5 docs: move insight error pages from vercel/front to canary (#94564)
### What?

Moves 14 insight-kind error pages from
`vercel/front/apps/next-site/content/errors-extra/` into this repo's
`errors/` directory.

### Why?

`nextjs.org`'s sync pipeline already clones `errors/` from canary on
every deploy. `errors-extra/` is meant for in-flight drafts. These pages
have stabilized, so they belong with the framework code they describe.

This unblocks Docs Link Validation in #94496: cross-links from this
repo's API docs (`cookies.mdx`, `headers.mdx`, `use-params.mdx`,
`use-pathname.mdx`, `generate-metadata.mdx`, `generate-viewport.mdx`,
etc.) to `/docs/messages/blocking-prerender-*` now resolve.

### How?

Copied each `.mdx` verbatim. No content changes. Frontmatter (`kind:
insight`) routes them through the FixOption renderer. Follow-up PR in
`vercel/front` will remove the `errors-extra/` copies; until then the
override wins on slug collision but the content is byte-identical.
