Introduce common Ruff configuration options to extension settings (#456)
Browse files Browse the repository at this point in the history
## Summary

This is a follow-up to astral-sh/ruff#10984,
which implemented support for common Ruff configuration options in
client settings. This PR exposes these new settings in the extension
configuration.

These settings are different from other extension settings, because they
don't have default values. Instead, if the user does not set them, they
will be sent as `null`, and the server will use project configuration
instead.

At the moment, `ruff server` does not actually resolve these settings
yet - settings resolution is introduced in
astral-sh/ruff#11062, which means that you'll
need to work from that branch to test this PR (and vice-versa).

## Test Plan

See the test plan in astral-sh/ruff#11062.
