[PATCH 4/4] python: enable testing for 3.13

[John Snow <jsnow@redhat.com>]

Python 3.13 is in beta and Fedora 41 is preparing to make it the default
system interpreter; enable testing for it.

(In the event problems develop prior to release, it should only impact
the check-python-tox job, which is not run by default and is allowed to
fail.)
