Martin Fischer 28c9263722 Automatically linkify option references in rule documentation
Previously the rule documentation referenced configuration options
via full https:// URLs, which was bad for several reasons:

* changing the website would mean you'd have to change all URLs
* the links didn't work when building mkdocs locally
* the URLs showed up in the `ruff rule` output
* broken references weren't detected by our CI

This commit solves all of these problems by post-processing the
Markdown, recognizing sections such as:

    ## Options

    * `flake8-tidy-imports.ban-relative-imports`

`cargo dev generate-all` will automatically linkify such references
and panic if the referenced option doesn't exist.
Note that the option can also be linked in the other Markdown sections
via e.g. [`flake8-tidy-imports.ban-relative-imports`] since
the post-processing code generates a CommonMark link definition.

Resolves #2766.

relative-imports (TID252)

Derived from the flake8-tidy-imports linter.

Autofix is sometimes available.

What it does

Checks for relative imports.

Why is this bad?

Absolute imports, or relative imports from siblings, are recommended by PEP 8:

Absolute imports are recommended, as they are usually more readable and tend to be better behaved...

import mypkg.sibling
from mypkg import sibling
from mypkg.sibling import example

However, explicit relative imports are an acceptable alternative to absolute imports, especially when dealing with complex package layouts where using absolute imports would be unnecessarily verbose:

from . import sibling
from .sibling import example

Options

Example

from .. import foo

Use instead:

from mypkg import foo
