Python 3.7 is EoL

[cpburnz]

I am looking into dropping support for Python 3.7 (which become EoL on 2023-07-26) for pathspec. yamllint is the one major dependent of pathspec that I'm aware of that still supports Python 3.7. ansible-lint which is a dependent of yamllint has already moved to Python 3.9+. Do you intend to continue or drop support for Python 3.7?

Hello @cpburnz, this sounds like a good idea! Would you like to contribute by making a commit similar to e8391de (that dropped support for Python 3.6)? It would need a slight adaptation because of the switch to pyproject.toml.
