Python version is fixed to 3.8

[joleroi]

The Readme of this repo states that a Python version "Python >= 3.8" is required. In the Pipfile, however, the version is fixed to 3.8. This is a little confusing.

It worked for me with Python 3.11.0 after editing the Pipfile to require only "python_version = 3".

This is of course a minor issue but can be frustrating for beginners.
