Use stable instead of edge docker images in Auto DevOps jobs
Switch the docker images to use tags corresponding to Docker stable releases instead of edge releases.
The stable channel provides reliable updates every quarter, while edge gives new features every month. For Auto DevOps, I think it makes more sense to stick with reliable Docker releases, since the goal of Auto DevOps is not intrinsically to test new Docker features.
