tweak(ci): Automate pre-commit runs

[arrdem]

This is an opinionated change, and to be very clear the opinion is mine. Linters which can also do formatting should not be allowed to break CI. If there is a programmatically defined "right way" things should be done and tooling can do it, no purpose is served in making a human rerun a tool to apply that formatting.

Extend the pre-commit CI step so that it will commit (as @aspect-marvin) any formatting changes and push them back to the branch.

The motivation for doing this isn't just my own annoyance with pushing lint commits, but also so that PRs from @renovate-bot will trigger updates to the Gazelle manifest (or other code) so that those PRs can auto-merge.
