AttributeError: 'XSOEnumMixin' object has no attribute 'name'

Description of the bug

I just updated to fedora 38 and I'm having this issue when trying to run moodle-dl as expected in my normal setup.

Even running moodle-dl --help has the same issue.

`Traceback (most recent call last):
  File "/usr/lib64/python3.11/enum.py", line 260, in __set_name__
    enum_member._value_ = enum_class._member_type_(*args)

                                  ^^^^^^^^^
AttributeError: 'XSOEnumMixin' object has no attribute 'name'

The above exception was the direct cause of the following exception:

Steps to reproduce the issue

xD I somehow have the feeling we should move away from aioxmpp

Can confirm, just upgraded moodle-dl as I haven't done so in months. Same error as @daniarla occurs when running moodle-dl.

Do you have an estimate when this bug is fixed or where it first occurred? I tried downgrading to the last minor release but still not luck. The very original 2.0 works for me

[C0D3D3V]

I think it is a bug with aioxmpp I guess it should work with versions that do not use aioxmpp. But I can make a fix tonight or tomorrow. I would also welcome if someone does a PR, we could just make a try except to handle the import error of aioxmpp for now, and I would also welcome a move to python-nbxmpp https://dev.gajim.org/gajim/python-nbxmpp since that is used by thousends of users it should be more stable.

[C0D3D3V]

just for the record the first version with aioxmpp is 2.2.0.0 https://github.com/C0D3D3V/Moodle-DL/releases/tag/v2.2.0.0

[jfrcom]

@C0D3D3V I'm not able to pinpoint where exactly the error occurs. Would you be able to point me into the right direction?

Please test if the latest release, fixes the issue
