docs(docs-infra): create code block for links to methods (#50110)

Before this commit, links to methods had to rely on a custom title (or the method name would be displayed).

With this commit, {@link MyClass#myMethod} will ouput a link as `MyClass#myMethod`.
This has a 2nd advantage : We can now rely on the validation by the `checkAnchorLinksProcessor` to ensure the method actually exist.

This commit is part of #50110 to improve linking in the documentation.
