Backtick-quoted links with no explicit target in rule documentation

[InSyncWithFoo]

FAST002's rule documentation reads:

The [FastAPI documentation] recommends the use of [`typing.Annotated`] for
<!-- ... -->
[fastAPI documentation]: https://fastapi.tiangolo.com/tutorial/query-params-str-validations/?h=annotated#advantages-of-annotated
[typing.Annotated]: https://docs.python.org/3/library/typing.html#typing.Annotated

This is how PyCharm renders it:

And GitHub:

The FastAPI documentation recommends the use of [typing.Annotated] for

CommonMark dingus is no different:

<p>The <a href="https://fastapi.tiangolo.com/tutorial/query-params-str-validations/?h=annotated#advantages-of-annotated">FastAPI documentation</a> recommends the use of [<code>typing.Annotated</code>] for</p>

Links of the form [`something`] is not very well-recognized by renderers and thus should be avoided, similar to the "automatic" option links discussed in #14348.

The easiest way to fix them would be to use an explicit target:

The [FastAPI documentation] recommends the use of [`typing.Annotated`][typing-annotated] for
<!-- ... -->
[fastAPI documentation]: https://fastapi.tiangolo.com/tutorial/query-params-str-validations/?h=annotated#advantages-of-annotated
[typing-annotated]: https://docs.python.org/3/library/typing.html#typing.Annotated

GitHub handles this much better:

The FastAPI documentation recommends the use of typing.Annotated for

And so does CommonMark dingus:

\[`[^`]+`\](?![\[(]) returns 359 hits, while that of \[`(?!lint\.)[^`]+`\](?![\[(]) is 67. This shows that the vast majority of broken links are option pseudo-links (and even then, there are still line-length, target-version and other top-level options that haven't been filtered out).

Fixable links can be found using \[`([^`]+)`\](?![\[(])(?=.*+(?>\R///.*)*\R/// \[\1) (or \[`([^`]+)`\](?![\[(])(?=.*\\n\[\1\]:) if you prefer working with ruff rule --all --output-format=json).
