RuntimeWarning: Running interpreter doesn't sufficiently support code object introspection

[nbro10]

Info

1. zeep version: 4.2.1 (but the issues occurs with version 4.0.0 too)
2. To reproduce this issue, just create a file zeep_problem.py with e.g. this import from zeep.exceptions import Fault. This issue happens because there's a class Settings in zeep/settings.py (https://github.com/mvantellingen/python-zeep/blob/main/src/zeep/settings.py) with the decorator @attr.s(slots=True), then run pytest zeep_problem.py
3. Python version 3.11.2 (this also happens with 3.11.5), both installed with pyenv
4. Pytest 6.2.5
5. MacOS: 13.5.1 (22G90) (M1)
