[FIX] Pin Python version for version <=12.0

pylint pulls a version of wrapt that is broken on Python 3.11. See
<GrahamDumpleton/wrapt#196>.

This breaks pre-commit for any devs running a modern OS.

Because we already pinned flake8 to Python 3.6 to circumvent a similar
problem, we now simply do it universally to prevent that whole class of
problems.
