[Feature Request] Remove gym dependency

[ernestum]

🚀 Feature

Remove gym dependency.

Motivation

I think we don't need gym support any more and it clutters our dependencies.

Pitch

• Remove the dependency from requirements.txt and setup.py.
• Remove the gym-specific sections in the gym_patches.py file.

Alternatives

Keep it in because we still need it for some reason.

Additional context

No response

Checklist

• [X] I have checked that there is no similar issue in the repo

We need https://github.com/araffin/pybullet_envs_gymnasium and then we can remove gym dependency I think.
