dag parse stdout goes to warning on celery worker

### Body not sure why but here's an example sample code ``` from time import sleep from airflow import DAG from airflow.decorators import task from airflow.models.baseoperator import chain_linear with DAG(dag_id="dag1", catchup=False): @task def the_task(): sleep(10) tasks = [] for num in range(3): tasks.append(the_task.override(task_id=f"task_{num+1}")()) chain_linear(*tasks) print("HI I AM HERE") ``` celery worker output <img width="405" alt="image" src="https://github.com/user-attachments/assets/3d1480e5-520d-47f7-bc1d-16b064fc1f3e"> this can pollute worker logs if you have a really chatty dag ### Committer - [X] I acknowledge that I am a maintainer/committer of the Apache Airflow project.
