setup.py in https://www.gymlibrary.dev/content/environment_creation/#make-your-own-custom-environment

Dear Developers,

My setup:
ubuntu 23.04
Python 3.11.4 (main, Jun 9 2023, 07:59:55) [GCC 12.3.0] on linux

When running instructions for my own environment in
https://www.gymlibrary.dev/content/environment_creation/#make-your-own-custom-environment

the suggested procedure:

git clone https://github.com/Farama-Foundation/gym-examples
cd gym-examples
python -m venv .env
source .env/bin/activate
pip install -e .

resulted weird errors (something pygame relatated ):

Collecting pygame==2.1.0
  Using cached pygame-2.1.0.tar.gz (5.8 MB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

      Hunting dependencies...

Tried to add some depencies with sudo apt install but got no help.
Instead updating setup.py fixed the thing (at least installation was ok)

old line in setup.py
install_requires=["gym==0.26.0", "pygame==2.1.0"],
new line in setup.py
install_requires=["gym>=0.26.0", "pygame>=2.1.0"],
