[Feature request] Add docstrings to rl_games fork (python3.11 branch)

[d-kleine]

While working on a new Isaac Lab project, I just noticed that the forked rl_games doesn't contain any docstrings:
https://github.com/isaac-sim/rl_games/tree/python3.11

Unfortunately, the fork does not allow any issue reports or discussions, therefore I'm requesting the feature here:

• The missing docstrings seem to originate from the original repo.
• Isaac Lab v3.0.0-beta2 uses the package isaaclab_rl, which uses the python3.11 branch of that fork for train.py and play.py scripts:
  

  IsaacLab/source/isaaclab_rl/setup.py

  Lines 44 to 48 in 7d2f5a5

  	"rl-games": [
  	"aiohttp==3.13.3",
  	"rl-games @ git+https://github.com/isaac-sim/rl_games.git@python3.11",
  	"gym",
  	"standard-distutils",

• Currently, it's quite hard to understand the code without any documentation. Would it be possible to add docstrings to the fork, or would it be better to report this issue in the original repo?
