Create GitHub Action to run codespell and ruff

[cclauss]

This Action uses minimal steps to run in ~5 seconds to rapidly:

• find typos in the codebase using codespell, and
• lint Python code using ruff and provide intuitive GitHub Annotations to contributors.

Also added a .pre-commit-config.yaml because .pre-commit.ci is running unconfigured on this repo.

Thanks 👍. I would suggest to squash the commits, or we can do it at merge time, too.
