Do Not Recommend Python 3.9

[Connor9994]

This is an absolute nightmare to try to "install each package individually." The NeMo library uses type hinting syntax (the | operator for unions) that's only available in Python 3.10 and newer.

It is NOT fun to fix it to work on 3.9, I would recommend just removing that suggestions entirely.

I agree with you about it being a nightmare, no one should be using 3.9 anyway but if someone has to use it, they can but after going through the dependency hell, As for nemo, the solution is to downgrade, nemo 1.20 is supported for example but I pinned in the requirements to avoid conflicts in other dependencies
