Setting a large PASSWORD_DURATION_SECONDS causes an error

Setting PASSWORD_DURATION_SECONDS to a large value gives an overflow error.

# settings.py
# 23992800719976 seconds
PASSWORD_DURATION_SECONDS = 24 * 9999**3

Traceback (most recent call last):
  File "[DIR]/site-packages/password_policies/middleware.py", line 186, in process_request
    self.check = PasswordCheck(request.user)
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^

OverflowError: date value out of range

Tested with python 3.12.

I think worth catching and setting the value to timedelta.max.
