title: Github Package Registry not overwriting tag when pushing a docker image
body: <p>I've pushed a docker image named <code>com.tejas:tejas-api:dev</code> to the github package registry. Now, when I again push the same image name (having updated code) on to the registry, it gets pushed successfully, but does not update the image. As a result, now I have two image versions: dev (with the build time from my first deploy), and docker-base-layer (with build time of my second and most recent deploy).</p>

  <p>Am I doing something wrong? Or is it a GitHub Package Registry bug?</p>
