Dropped support for Airflow < 3.1.0

The chart now requires Apache Airflow 3.1.0 or above. If you need to deploy older versions, use a chart from the 1.x line.

The following values are no longer accepted and must be replaced:

• webserver.* (entire section) → use apiServer.*
• webserver.defaultUser.* → use createUserJob.defaultUser.*
• webserver.allowPodLogReading → use apiServer.allowPodLogReading
• webserverSecretKey → use apiSecretKey
• webserverSecretKeySecretName → use apiSecretKeySecretName
• webserverSecretAnnotations → use apiSecretAnnotations
• enableBuiltInSecretEnvVars.AIRFLOW__WEBSERVER__SECRET_KEY → use enableBuiltInSecretEnvVars.AIRFLOW__API__SECRET_KEY

The following executors are no longer supported:

• LocalKubernetesExecutor
• CeleryKubernetesExecutor

Other behavior changes:

• dagProcessor.enabled default is now true (was null, which previously resolved to true on Airflow 3 anyway).
• config.webserver.enable_proxy_fix and config.scheduler.standalone_dag_processor defaults removed from values.yaml.
