Adding new dependencies for ManiSkill2 clean rl

[StoneT2000]

Problem Description

I'm running poetry lock to generate a new lockfile, is it meant to be super slow (going on about half an hour now)?

I assume this is what I should be doing since I'm trying to do #366 right now (we just finally upgraded to gymnasium so can work on a PR now). The only change atm is to pyproject.toml by adding mani_skill2 = ["mani_skill2"] to the poetry.extras part.

Checklist

• I have installed dependencies via poetry install (see CleanRL's installation guideline.
• I have checked that there is no similar issue in the repo.
• I have checked the documentation site and found not relevant information in GitHub issues.

An aside, I had some issue installing Pyyaml although I wasn't sure if it's because of me or poetry or cleanrl. I can install older versions of Pyyaml (5.3.1) but not the one allowed in cleanrl (5.4.1). I did a temp fix by just pip installing the older version for now just to get my side working. Seems related to yaml/pyyaml#601 wasn't sure if there is a fix.
