Support for Python 3.11

Importing the github module gives an error; the error comes from deprecated -> wrapt, which uses inspect.formatargspec, which was deprecated since Python 3.5 and removed in Python 3.11.

Inizia riproducendo il problema di importazione segnalato con Python 3.11 e ispeziona la catena delle dipendenze attraverso deprecated, wrapt e inspect.formatargspec mostrata nel traceback. L’attività è completata quando l’importazione di github riesce su Python 3.11 senza l’ImportError segnalato; le informazioni fornite non identificano alcun file del repository né alcun test da eseguire.
