ManiSkill2 - Fast Visual RL robotics cleanrl baselines

[StoneT2000]

Opening an issue on adding ManiSkill2 cleanrl baselines. The primary reason is to have good baselines and leverage the fast GPU-accelerated visual rendering of ManiSkill2 for tackling robotics envs. The plan is to include a PPO and SAC implementation (following their continuous variants implemented for mujoco with modifications to support parallel envs for SAC)

ManiSkill2 looks awesome. We would love to have a CleanRL variant for it. I have updated the contribution process here https://docs.cleanrl.dev/contribution to help get started.

Quick update: will make a PR once ManiSkill2 has upgraded officially to gymnasium, which can be followed here: https://github.com/haosulab/ManiSkill2/pull/76
