@heliocastro I was looking once more at the scripts in ./github/workflows and for consistency with the other scripts what do you think of renaming "docker-ort-runtime.yml" to something like build-and-deploy-ort-container-image-runtime? And change the name from "name: Mega Docker runtime image" to "name: Build and Deploy ORT Runtime Container Image?

On this PR i already moved the Mega name away. Renaming the workflows was really too much i think, and the only sensible change as @fviernau mentioned is the name of the PR itself.
So my vote is keep the way it is only with the name change.
