deprecation feature patch

Google Cloud's Managed Service for Apache Airflow (Cloud Composer) introduces new Airflow 3.3.1, 3.2.2, 2.11.1, and 2.10.5 builds across Gen 2 and Gen 3 environments. A key feature now allows snapshot-based migration from Airflow 2.11.1 to Airflow 3, currently rolling out in specific regions. This update aims to simplify upgrades to newer Airflow versions for users with compatible DAGs. Additionally, several older Composer versions and builds have reached their end of support, necessitating user upgrades.
