Apache Airflow version
Other Airflow 2 version (please specify below)
What happened
We installed 2.4.0 like this:
apache-airflow[crypto,postgres,docker,cncf.kubernetes,kubernetes,sqlite,statsd]==2.4.0
Our previous Docker image, built sometime in January, worked fine. Building it today results in broken Airflow, with this in the UI:

This is the text:
Broken DAG: [/usr/local/airflow/dags/dag_generator.py] Traceback (most recent call last):
File "/usr/local/lib/python3.8/site-packages/airflow/providers/cncf/kubernetes/operators/pod.py", line 51, in <module>

ImportError: cannot import name 'PodOperatorHookProtocol' from 'airflow.providers.cncf.kubernetes.utils.pod_manager' (/usr/local/lib/python3.8/site-packages/airflow/providers/cncf/kubernetes/utils/pod_manager.py)
If I enter the container and dig around site-packages/airflow/, I can indeed verify that PodOperatorHookProtocol is not in the pod_manager.py file.
I found a discussion here about this change, with some questions raised about the potential implications of the work (#31298). Is this related?
