Upgrade to Sphinx v7 - Githubissues

The issues are caused by this block, which was a hack to get Sphinx to support class properties.
# conf.py
ArrayMeta_properties = [
    member for member in dir(galois.Array) if inspect.isdatadescriptor(getattr(type(galois.Array), member, None))
]
for p in ArrayMeta_properties:
    # Fetch the class properties from the private metaclasses
    ArrayMeta_property = getattr(galois._domains._meta.ArrayMeta, p)

    # Temporarily delete the class properties from the private metaclasses
    delattr(galois._domains._meta.ArrayMeta, p)

    # Add a Python 3.9 style class property to the public class
    setattr(galois.Array, p, classproperty(ArrayMeta_property))

    # Add back the class properties to the private metaclasses
    setattr(galois._domains._meta.ArrayMeta, p, ArrayMeta_property)
