Cannot deactivate File-based logs for at processor

### Under which category would you file this issue? Airflow Core ### Apache Airflow version 3.3.0 ### What happened and how to reproduce it? ## Goal Completely disable file-based logs from dag processor. ## Context I Run airflow. I Notice that dag_processor creates many logs under `/opt/airflow/logs/dag_processor`. In fact, this directory eventually grows multiple GBs large and eats all available space. I can create some log rotator / archiver, but in fact I do not need the `dag_processor` logs at all so **I would very much prefer to deactivate them completely**. ## What I tried 1. Setting `[logging] --> dag_processor_log_target = stdout` and restarted airflow. Intuitively I would expect that this would work, but unfortunately the directory still being created and filled with multiple MBs per day.
