[Proposal] Python version included in doc pages.

[lindsayfowler]

Proposal

I suggest the documentation pages specify which version of Python to use.

Motivation

The libraries are very picky with regard to versions of everything. And knowing which python to use would be helpful. I cannot tell you how many times I start a tutorial and end up wasting hours trying to find a setup that works.

Pitch

#The code and tools used in this page are compatible with python 3.9.
for https://gymnasium.farama.org/introduction/create_custom_env/
or just put it in:
https://gymnasium.farama.org/introduction/basic_usage/
if it is indeed the version we should use 3.8 failed.
