Replicating environment in `paint` and `earl_benchmark` failed due to metaworld config

[sanggusti]

When building the project by using paint/conda_env.yml it returns:

Pip subprocess error:
  Running command git clone -q https://github.com/rlworkgroup/metaworld.git /tmp/pip-install-788dyw68/metaworld_e520cd838e2f44e088497125aeb659bd

The resolving solution for this is by changing the paint/conda_env.yml and earl_benchmark/env/yml content of packaging from rlworkgroup into git+https://github.com/Farama-Foundation/Metaworld.git@04be337a12305e393c0caf0cbf5ec7755c7c8feb as the new maintainer of metaworld is changing from rlworkgroup to Farama-Foundation (https://github.com/Farama-Foundation/Metaworld). I'll attach a pull request to help to resolving this issue.

I really appreciated your work and your paper is amazing. I'm currently learning your methodologies and best of luck on your further project!
