Describe the bug

Opening a record with a DateTime type column in the composite primary key will result in a 500 error.

The object_identifier_values() function in helper.py fails to convert to Python's datetime.datetime type, resulting in an error.

Steps to reproduce the bug

1. Create a model which contains a PK with a DateTime value and other PK.
2. Create an admin view for that model.
3. Try to access the admin view and the detail/edit view or deleting the record. You will get a 500 error.

The test code to reproduce is below.

class PersonWithDateTime(Base):
    __tablename__ = "users_with_datetime"

    family_id = Column(String, ForeignKey("family.id"), primary_key=True)
    member_id = Column(Integer, primary_key=True)
    version = Column(String, primary_key=True)
    date = Column(DateTime, primary_key=True)


def test_multi_pk_id_values_with_datetime_column():
    def id_values(ident):
        return object_identifier_values(ident, PersonWithDateTime)

    assert id_values("Johnson;7;A;2024-01-01 10:00:00") == ("Johnson", 7, "A", datetime.datetime(2024, 1, 1, 10, 0, 0))

Expected behavior

Records containing DateTime type as a composite primary key can be viewed and edited.

Actual behavior

Server error.
