Remove unused imports in tests #134357
Description
Feature or enhancement
Proposal:
There are unused imports in the tests. There have been previous efforts to remove them from the stdlib and tests:
I'll remove some from the tests and add a lint rule to prevent new ones. Often they're forgotten when refactoring code or removing deprecations.
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere
