Lint: Update Ruff config

[hugovk]

I didn't get a chance to review #3429 before merge, so here are some suggestions.

https://github.com/astral-sh/ruff-pre-commit says (emphasis mine):

Ruff's pre-commit hook should be placed after other formatting tools, such as Black and isort, unless you enable autofix, in which case, Ruff's pre-commit hook should run before Black, isort, and other formatting tools, as Ruff's autofix behavior can output code changes that require reformatting.

Also only enable GitHub formatting for GitHub Actions, not the user's local console.

And also remove --diff, it prevents the formatting and annotation.
