pyupgrade: convert to new style classes These were likely missed when the bulk of the classes got this change back in 642e31cb55f0. These were rewritten using a hacked version of `pyupgrade` 3.19.1 that enabled only the `new_style_classes` fixer. See 24ee91ba9aa8 for details. It's probably better to fix the thirdparty and contrib code upstream, but these are small changes, like those made locally in the past here. I don't feel like pulling down and testing potentially a lot of changes just to satisfy this linter.
