chore: Update minimum required python version to 3.10

[szaher]

What this PR does / why we need it:
python 3.9 EOL is end of October as per https://devguide.python.org/versions/
I suggest we move to python3.11 directly which provides better performance.

Shall we still support 3.10?

Yes, I would suggest we jump to 3.10 first.
IMO, we should support 3.9 for SDK v0.2 release at least.
The 3.9 EOF is October 2025, and I would imagine we still have users on that version: https://devguide.python.org/versions/

We also need to update Trainer and Katib
