Python base image is shared between CI and PROD image (#12280)
Python base image is shared between CI and PROD image (#12280)

When you are building CI images locally you use the CI
base images from apache:airflow/python* now to maintain
consistency and avoid often rebuilds. But when you build
prod images, you would accidentaly override it with the
python base image available in python repo which might be
different (newer and not yet tested in CI). This PR
changes it to use the same base image which is now
tagged in Apache Airflow's dockerhub repository.
