Upgrade to python 3.11

[sash-a]

Please describe what needs to be maintained?

Upgrade python version, we are on 3.9, which is almost 3 years old at this point.

Big reason for this is the discussion in #940 about having generic named tuples, which isn't possible in 3.9 or 3.10. But 3.11 brings other benefits also.

I have tested this locally and it worked out of the box.

Solution we found in #940 was from typing_extensions import NamedTuple. Solves the immediate issue, although upgrading to 3.11 would still be nice, just not as urgent

I have tested python 3.12 and it seems to work without issue, we should drop support for 3.9 (and possibly 3.10 also) soon as it is nearing end of life.

I think this is a good idea - it would be nice to have language support for pattern matching too!

Maybe along with this upgrade the pre-commit #1036 or move to ruff as suggested here #1002
