Explanation
Issue
#12891is limited to the Dataflow Engine image builder. The pull request also changes unrelated builder images, test images, DM Dockerfiles and configuration, lint targets, multiple developer documents, and several module dependency declarations. The linked issue states that the other image types are unaffected, so these changes are not required to fix the engine image build.
