### Apache Airflow version

2.5.3

### What happened

When I call the airflow initdb function, it outputs these lines to the log

INFO  [alembic.runtime.migration] Context impl PostgresqlImpl.
INFO  [alembic.runtime.migration] Will assume transactional DDL.

### What you think should happen instead

There should be a mechanism to disable these logs, or they should just be set to WARN by default

### How to reproduce

Set up a new postgres connection and call:

from airflow.utils.db import initdb
initdb()
