PSA: Fix for plotting issue in ubuntu 22.04

[titonbarua]

If you see graphs not popping up in Ubuntu 22.04, it's because of matplotlib version 3.9.0. The fix is to install version 3.8.0 of this library using pip3 install matplotlib==3.8.4.

When I tried to run

panda.teach(panda.qz)

from the README.md, I got.

TypeError: Slider.__init__() takes 5 positional arguments but 7 were given

similarly, it was solved by pip install matplotlib==3.8.4.

I think full list of working package versions (such as requirements file for conda) will come handy.
