The description of `use_zip_binary()` is incorrect.

https://github.com/apache/airflow/blob/318f18f5a835f457c6a68426a476af89ace0c7e7/airflow/example_dags/example_kubernetes_executor.py#L69-L70

Additionally, the name `use_zip_binary` is not very telling. Maybe `assert_zip_binary` (based on what the function actually does)?
