- all agents return an observations synchronously (instead of having steps where only one agent returns an observation) - in case the agent sends a TerminationStep *and* a DecisionStep after, the reward from the termination step should be taken (but for observations it's the other way around because of SB3 convention) - `agents` attribute should store agents even if they have *just* finished (they should be removed the step after) - fixed a bug where a continuous action vector was assigned len(action) * action[0] - fixed double removal of an agent from _live_agents for ParallelEnv

Proposed change(s)
I adjusted the Unity Pettingzoo Wrapper to support the gymnasium interface (gymnasium>=0.25).
This includes:
terminated, truncatedon stepinfoon resetseedandoptionson resetmodeon renderAdditionall, I fixed interface problems with pettingzoo implementation:
agentsattribute should store agents even if they have just finished (they should be removed the step after)Also I bumped the dependencies for pettingzoo to 1.22.0 (because this is there Gymnasium support started on their side).
Useful links (Github issues, JIRA tickets, ML-Agents forum threads etc.)
This also could be helpful for: #5890
