URL: https://github.com/apache/airflow/issues/32316
### Apache Airflow version
2.6.2
### What happened
I installed `apache-airflow` and attempted to set up the db via:
`airflow db init`
but it fails with the following pydantic error:
```
DB: sqlite:////Users/username/airflow/airflow.db
/Users/username/Desktop/project_root/.venv/lib/python3.9/site-packages/pydantic/_internal/_config.py:257
UserWarning: Valid config keys have changed in V2:
* 'orm_mode' has been renamed to 'from_attributes'
