Review comment:
Sure, I've added this example to [the docs](https://github.com/apache/airflow/pull/5010/files#diff-35b9954899f172a9d4e1b8488cade790R85), and added examples for all removed variables to [UPDATING.md](https://github.com/apache/airflow/pull/5010/files#diff-bb7ee25332d5fdca3ead2f545d72b359R32).
