AttributeError: module 'bcrypt' has no attribute '__about__'

radicale --version: 3.1.8
python --version: 3.11.6
bcrypt version: 4.1.3

Just after starting Radicale, I get the following error:

(trapped) error reading bcrypt version
Traceback (most recent call last):
  File "/usr/lib/python3.11/site-packages/passlib/handlers/bcrypt.py", line 620, in _load_backend_mixin
    version = _bcrypt.__about__.__version__
              ^^^^^^^^^^^^^^^^^
AttributeError: module 'bcrypt' has no attribute '__about__'

The bcrypt team seems to have already pointed out a solution here: pyca/bcrypt#684

Best to circumvent this is replacing passlib by direct bcrypt as proposed above.
