Stop installing custom Docker version

GitHub Actions workers have Docker preinstalled, so there is no need to fetch and install a custom installation of Docker. Additionally, there were some issues with parsing out the image properties such as repository name, image name and image tag. Those are all now solved. The Test Run workflow will also check to ensure the action outputs an image URL.

Thanks to my good friend Stephen Edwards for helping me with this one.
