### Apache Airflow version

### What happened
Starting from 2.3.2 and 2.3.3 getting a warning
`Jul 10 10:34:15 lt-hkg1-avm04 airflow:
/usr/local/lib/python3.9/site-packages/airflow/configuration.py:532
DeprecationWarning: The sql_alchemy_conn option in [core] has been moved to the
sql_alchemy_conn option in [database] - the old setting has been used, but
please update your config.`
but after moving that parameter to database, airflow is not starting.
