Secrets from Airflow configuration are not masked in task logs

### Apache Airflow version 3.1.8 ### If "Other Airflow 3 version" selected, which one? _No response_ ### What happened? Secrets from Airflow configuration are not masked in task logs if printed with stdlib or structlog. This has to be culprit: https://github.com/apache/airflow/blob/e3c10eae08cd8c0d28f1edaab24e11bd25606d6c/task-sdk/src/airflow/sdk/execution_time/supervisor.py#L2094 ### What you think should happen instead? Secrets should be masked. ### How to reproduce 1. Run locally breeze 2. Deploy DAG ``` import datetime from airflow import DAG from airflow.configuration import conf from airflow.providers.standard.operators.python import PythonOperator import structlog structlog_logger = structlog.get_logger() def _print(): for section, key in [ ("webserver", "secret_key"), ("api", "secret_key"), ("api_auth", "jwt_secret"), ]: print("print", section, key, conf.get(section, key, fallback=None)) structlog_logger.info("structlog " + section + " " + key + " " + conf.get(section, key, fallback="")) with DAG( dag_id="print_secrets", schedule=None, start_date=datetime.datetime(2010, 1, 1), catchup=False, ) as dag: operator = PythonOperator( dag=dag, task_id="task", python_callable=_print, ) ``` 3. Observe secrets visible in the task logs (Airflow UI) Example: <img width="2126" height="761" alt="Image" src="https://github.com/user-attachments/assets/54f9ab54-d0f3-4719-ad0d-cac1466c5246" /> ### Operating System Linux ### Versions of Apache Airflow Providers _No response_ ### Deployment Docker-Compose ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
