Move docker image to registry to address flaky test (#129660)

* Instead of creating a new Docker image on-the-fly, it is better to create a persistent image and upload it to Docker Registry. This will help tests dependent on this image be resilient to transient issues such as #126694 and also speed up execution.

* fix name

(cherry picked from commit 22390d7)
