Add RecordVideo wrappers

[nightly]

Description

Provides a direct port of the RecordVideo wrapper from Gymnasium to PettingZoo. Currently, you'd have to implement your own wrapper for this or rely on a wrapper from something like SB3 or TorchRL.

List of changes:

• Implements the wrappers separately for base/AEC environment type and parallel environment type, as done so for other wrappers in the repo.
• Updates pyproject.toml for pettingzoo[other] packages to add MoviePy which is needed for rendering/recording.
• Adds a new test file for the Record Video wrappers, testing both AEC and Parallel on Piston Ball (this test is also adapted from Gymnasium).

Some documentation needs to be added (this can be done if the contribution itself is approved). One improvement would be abstracting out some of the logic between the two wrappers, but I've left it as-is for now.
