Shared workflow to update pre-commit hooks.

All steps pass except creating the PR, which can't happen from a PR so until we merge 322 and trigger the workflow against main it won't work.

What is the reason to add pre-commit autoupdate? What does it do for us? Also, could you add CODEREVIEWERS correctly? Now this repo doesn't ask zuos-reviewers for a review automatically.

It updates the hook versions. So they don't lag (too far) behind the main dependencies managed by dependabot.

Dependabot don't support updating .pre-commit-conf.yaml so this is the next best option.
