Improve `operator.itemgetter.__call__` generic following mypy 1.11 fix
https://github.com/python/mypy/issues/14032 has been fixed in mypy 1.11.0 (I didn't go as far as to search for the exact commit).
This updates operator.itemgetter to include a change I originally wanted to do in https://github.com/python/typeshed/pull/9117, removes the outdated comment, and adds a regression test.

There seems to be a variance issue in the interaction with map and/or groupby. But I honestly can't quite figure it out.

I'm also not sure why this doesn't work. Still I think for now it's best to postpone (i.e. close) this PR, until this works better.
If you close this, please make it an issue. The behaviour here feels unexpected and seems worth investigating.
