Subject: [PATCH] Test against Python 3.11, 3.12 and 3.13 in CI

Previously local and CI tests would only run against Python 3.10
and older.

Now, Python 3.11, 3.12 and the prerelease versions of 3.13 are
tested too. (If installed locally)

This improves test coverage, and also gives more flexibility when
running nox locally, since there is a greater chance it will find a
matching Python version rather than skipping all tests if eg only
newer Python is installed.

I've also upgraded the setup-python and checkout actions to
their latest versions:
