Is your feature request related to a problem? Please describe.

As of Python 3.9, it is no longer necessary to do this kind of thing:

from typing import List

def foo() -> List[int]:
    return [1, 2, 3]

You can instead do:

def foo() -> list[int]:
    return [1, 2, 3]

Describe the solution you'd like

We should remove these uses of typing.Dict, typing.List, typing.Tuple and typing.Set and replace with built-in types where possible.

This might be a good job for Copilot.

Describe alternatives you've considered
