Add support for Python 3.10-3.12 and drop EOL 3.5-3.7

[hugovk]

Also modernise the GitHub Actions workflows and upgrade Python syntax with https://github.com/asottile/pyupgrade --py38-plus.

3.12 will fail until #160 is merged; I can remove it from this PR if you want to merge this first.

Hello @hugovk, thank you for this. Indeed I was having issues with launching the GitHub action for your earlier PR

@hugovk sorry for the naive request but i can't seem to be able to merge this. Here's what i'm seeing:

Is there a way i can bypass this "required" build of python 3.5?

Thanks

Not a naive question at all! Do you have admin access to this repo?

If so, have a look at https://github.com/rabbit/pysox/settings/branches and there'll be a branch protection rule.

You can edit it and remove the rules for the old ones, and optionally add the new ones.

Thanks @hugovk. Looks like i'm maintainer but not admin. I have notified the admin, Rachel Bitner, over email. Will report back soon
