Force scipy and lower maximum python version

Required for pip install -r source/requirements.txt on Windows after adding frccontrol. This is due to scipy being classified by poetry as a restricted dependency, so it prefers their maximum Python version over our own.

Does frc docs build on 3.10/11?

[Daltz333]

Yep. I'm daily driving it

The build instructions should be updated. It says 3.10 is incompatible.
