Test 3.11 final and 3.12-dev

[hugovk]

Python 3.11.1 is out, let's just say 3.11 to test the latest.

And we can also now test 3.12-dev.

---

And maybe it's time to drop EOL Python 2.7, 3.5 and 3.6?

It would allow modernising the code to use newer features, and reduce the resources used by the CI.

Thank you for PR! We will think about drop support for Python 2.7, 3.5 and 3.6.
