Only tag :latest image when default python version is used (#34182)

We should only tag :latest image when default image is used because
this step always tags `apache/airflow:X.Y.Z` (defaulti Python) to become
the `apache/airflow:latest`. This step was previously run for all Python
versions which could have two effects:

* if non-default image completed before the default such tagging
  would fail as the `apache/airflow:X.Y.Z` was not ready yet to
  be used as target of `apache/airflow:latesti` tag

* if non-default image completed later, it would be no-op because
  the `apache/airflow:latest` already pointed to `apache/airflow:X.Y.Z`
