Add Warning in Docs that only timezone aware data is supported

[mithun2003]

sqlalchemy.exc.DBAPIError: (sqlalchemy.dialects.postgresql.asyncpg.Error) <class 'asyncpg.exceptions.DataError'>: invalid input for query argument $3: datetime.datetime(2024, 5, 22, 8, 11, 40... (can't subtract offset-naive and offset-aware datetimes)
[SQL: UPDATE platform SET is_active=$1::BOOLEAN, is_live=$2::BOOLEAN, updated_at=$3::TIMESTAMP WITHOUT TIME ZONE WHERE platform.id = $4::INTEGER]
[parameters: (True, True, datetime.datetime(2024, 5, 22, 8, 11, 40, 307132, tzinfo=datetime.timezone.utc), 2)]

showing this error when i try to update my table.
The issue i think is in my tables the field updated_at didn't require timezone but the update code in fastcrud adding timezone in it so how to avoid that?

We don't support datetime without timezone since it's deprecated:

If that's actually the issue, just change it to timezone aware date
