pre-commit-hooks v6.0.0 requires Python >= 3.9. This repo still supports Python 3.7/3.8 (seepython_requires / tox env list), andtox -e misc runspre-commit, so contributors (or CI jobs) invoking pre-commit under 3.7/3.8 will fail to create the hook environment. Consider either pinningpre-commit-hooks to <6, or explicitly ensuring pre-commit runs with Python >= 3.9 (e.g., run themisc tox env only on >=3.9 and/or set adefault_language_version for python hooks).

I think it was okay for this to be non-blocking, but it makes a reasonable point--although it's been a long time since ourpre-commit hooks all worked on the lowest version of Python that GitPython supports, it may make sense to do something to make this clear.

I think Copilot is correct that we can usedefault_language_version to make the hooks run with a different version. This feels like it would be even better, but I'm not sure. I think it would be confusing to have that happen when running it from inside a virtual environment for an earlier version, and still not work if no such interpreter is available. Therefore I suspect just a comment, or even just a clear note in the readme, would be better. But I haven't looked into it.
