Enable fixes in pre-commit

[echoix]

Many tools can apply fixes in their pre-commit hooks. Some have them enabled by default, while others have two separate hooks, one without fixes and one with fixes, and users select the one they want, and others ask for users to override args in their pre-commit configuration.

For example:

• The hook fixes by default https://github.com/pre-commit/pre-commit-hooks/blob/f1dff44d3a9ae852957f34def96390f28719c232/.pre-commit-hooks.yaml#L137-L144
• Separate markdownlint-fix hook in https://github.com/igorshubovych/markdownlint-cli/blob/master/.pre-commit-hooks.yaml
• Fixing manually defined by users for ruff: https://docs.astral.sh/ruff/integrations/#pre-commit

Since zizmor has some fixes available, it would be nice to have the fixing functionality discoverable

Hey @echoix, thanks for opening an issue. Yeah, I'd be happy to take a PR adding another hook configuration to this repo for the fix mode, assuming it'll be backwards compatible with anybody using the current hook 🙂

Oh hmm, or rather: if what ruff does is just encourage people to pass --fix, I think we should probably do the same here rather than duplicate the hook. So I think this would be a documentation change rather than a change to the hook itself, if I understand correctly.

See OSGeo/grass#6808, but I didn't have a fix to apply yet, to see it working
