5.0: Update django.db.models.functions.datetime

[JaeHyuckSa]

I have made things!

Update stubs for django.db.models.functions.datetime for Django 5.0.

• django.db.models.functions.datetime
  • django.db.models.functions.datetime.TruncBase.__init__'s is_dst argument was removed
  • django.db.models.functions.datetime.TruncBase.is_dst was removed
  • django.db.models.functions.datetime.Trunc.__init__'s is_dst argument was removed

I have added the necessary __init__ and as_sql methods to accommodate the updates in Django 5.0.

the types on expression do not match django.db.expressions.Func which currently has this typed as Any -- notably these expressions go through parsing and (at the very least) accept str as well
