Typo in the requirements section of the README.md documentation

[helpingstar]

Problem Description

In README.md

If you are not using poetry, you can install CleanRL with requirements.txt:

# core dependencies
pip install -r requirements/requirements.txt

# optional dependencies
pip install -r requirements/requirements-atari.txt
pip install -r requirements/requirements-pybullet.txt
pip install -r requirements/requirements-mujoco.txt
pip install -r requirements/requirements-mujoco_py.txt
pip install -r requirements/requirements/requirements-mujoco.txt

pip install -r requirements/requirements/requirements-mujoco.txt

There is no requirements folder inside the requirements folder; it appears to be a typo or a folder that was lost in an update.

Checklist

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

Current Behavior

ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements/requirements/requirements-mujoco.txt'

Expected Behavior

Possible Solution

I think that line should be deleted.
