Pickling error in Python 3.11: `TypeError: code() argument 13 must be str, not int`

[alxmrs]

I've noticed this line causes an error on my machine: https://github.com/cubed-dev/cubed/blob/1ac50612e48882554f08951e0072559ead6b2e71/cubed/tests/test_core.py#L592

Looking around, I think this is a problem in Python 3.11, see https://github.com/python/cpython/issues/100316.
