Remove AST nodes deprecated since Python 3.8, with warnings since Python 3.12

[AlexWaygood]

Feature or enhancement

Proposal:

In #104199, we added deprecation warnings for AST nodes that had been deprecated in the docs since Python 3.8. They have now had deprecation warnings for two releases; it is time to remove them.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
