This PR will fail until 1.23.0 is released, but in the second to last commit you can see that every test besides Ray works with the most recent master install of PettingZoo, indicating that when we create the 1.23.0 release these tests should pass. We could keep them locked to the most recent master version of PettingZoo, which I think would make things simpler, and allow for future updates to the tutorials more easily, but I suppose in the case that we do need to update the tutorials and not do a release, we can change the requirements to explicitly do github master, otherwise we keep it like this for simplicity.
