Python 3.12 not supported

[mspreitz]

when starting RootTheBox directly out of a venv (without docker) it runs into an issue because the nose dependency seems not to be ready for Python 3.12

(rootthebox) ubuntu@ctf:~/RootTheBox$ python3 rootthebox.py
Traceback (most recent call last):

my current fix to get it still running is by just deleting the import nose line within the rootthebox.py - but I'm sure that this is not the best option
