1.9.4 release not backward compatible with Python 3.8

[nemesifier]

The latest release doesn't seem to work anymore with Python 3.8:

  File "/home/runner/work/openwisp-radius/openwisp-radius/openwisp_radius/saml/backends.py", line 2, in <module>
    from djangosaml2.backends import Saml2Backend
  File "/opt/hostedtoolcache/Python/3.8.18/x64/lib/python3.8/site-packages/djangosaml2/backends.py", line 43, in <module>
    class Saml2Backend(ModelBackend):
  File "/opt/hostedtoolcache/Python/3.8.18/x64/lib/python3.8/site-packages/djangosaml2/backends.py", line 75, in Saml2Backend
    ) -> tuple[str, Optional[Any]]:
TypeError: 'type' object is not subscriptabl

Downdgrading to 1.9.3 fixes the issue.

Is this intentional?
I would have expected such breaking change to be included in a new minor version (eg: 1.10.0), not in a bugfix release.

ciao Federico,
you are right, I had missed the removal of 3.8 as a breaking change, here #410

I have to remove the pypi package and create a brand new release including the warning about the breaking change in the changelog
