ci: fix some more warnings in pre_commit.yaml

Let's just use the latest python version. But now that we're not using the
system python, we need to install all the dependencies for the various
tools.

I didn't see where we actually use actions/cache, hopefully the
actions/setup-python bump fixes that warning.
