[For discussion] What Python versions should apio support?

[zapta]

Currently (Jan 20225) apio is tested with python versions 3.9/10/11/12/13. This issue is a proposal to limit the testing to the last three python versions, in this case 3.11/12/13, and possibly a release candidate for the upcoming 3.14.

A summary of python's versions
https://devguide.python.org/versions/

Motivation:

• Dropping old version allows to use newer features of the language. For example, we still can't use @override in apio.
• The more versions we target, the more work it is to make all of them happy.
• The test time is proportional to the number of versions we test.

Dropping versions 3.9, 3.10 from the test also means that apio doesnt support them and most likely will fail with those versions.

@Obijuan, @cavearr, any thoughts?

The change will be applied here
