Trac #32597: networkx selftests are broken, use pytest instead of nose

In Sage, `networkx` selftests which are run by `nose` are broken (perhaps just because of #32595). Upstream now relies on `pytest` for its selftests, see https://github.com/networkx/networkx/blob/main/INSTALL.rst URL: https://trac.sagemath.org/32597 Reported by: tmonteil Ticket author(s): Thierry Monteil Reviewer(s): Matthias Koeppe
