Upgrade Ruff configuration for v0.2.0

[charliermarsh]

Summary

Hopefully a welcome PR, but this upgrades Sphinx's Ruff configuration to reflect some of the changes we're making in v0.2.0. We use Sphinx in our ecosystem checks, and I wanted to do an example migration anyway, both for illustrative purposes and for my own testing. (This PR won't pass until we do the actual v0.2.0 release.)

Here's a summary of the relevant changes for Sphinx:

• show-source = true was replaced by output-format = "full". (This is a deprecation, not a removal, so changing it here merely removes the deprecation warning.)
• Rules ANN101 and ANN102 were deprecated. (Selecting them with preview enabled is now an error; selecting them outside of preview is a warning.)
• PGH001 was redirected to S307 (I enabled S307 and changed the # NoQA assertions, which would've continued to work, but with a deprecation warning).
• RUF011 was redirected to B035 (which you already have enabled, so I just removed RUF011, which would've warned).
• TCH006 was redirected to TCH010 to match the upstream plugin.

For completeness, these are the warnings that would've been raised:

warning: The `show-source` option has been deprecated in favor of `output-format`'s "full" and "concise" variants. Please update your configuration to use `output-format = <full|concise>` instead.
warning: `RUF011` has been remapped to `B035`.
warning: `TCH006` has been remapped to `TCH010`.

  Cause: Selection of deprecated rule `ANN102` is not allowed when preview is enabled.
