Fix the installation guide

[irekkosek]

Describe the bug Installation guide is obviously flawed with numpy and python versions mismatch.

To Reproduce Steps to reproduce the behavior: try following your own installation guide

I had the same issue and fixed it by manually replicating the changes here: https://github.com/Unity-Technologies/ml-agents/pull/6082/files

Also, I think you need Unity 2023.2+ ?

linux没有这个问题试过了，这个问题是window没有这个numpy的包，可以尝试使用pip官方的项目没问题的编译一次

The installation guide also suggests you can use newer versions of Python than 3.10.12. That does not seem to be the case. I made a PR to fix the docs but the CLA form is not worth changing a single line in the docs. https://github.com/Unity-Technologies/ml-agents/pull/6131/files

I got past this issue by changing numpy version in mlagent-env/setup.py to have a dependency on version 1.22.1 instead of 1.21.2. After that, following the instructions on their installation page (https://unity-technologies.github.io/ml-agents/Installation/) works.
