Apache Airflow helm-chart/1.22.0

Significant Changes

Minimum Helm version was updated to 3.19.0 (#66970)

Default Airflow image is updated to 3.2.2 (#67681)

The default Airflow image that is used with the Chart is now 3.2.2, previously it was 3.2.1.

The default will become false in Chart 2.0. If you rely on these environment variables, explicitly set enableServiceLinks: true, or migrate your code to use DNS-based service lookups.
