GitHub Action: Add git commit id to docker image tag

It’s super easy to tag and upload an docker image with the commit id of the current build. If you use the actions-hub/docker/cli@master action you just have to use the predefined environment variable github.sha.

    - name: Tag built container
      uses: actions-hub/docker/cli@master
      args: tag tictactoeserver:1.0.0${{ github.sha }}

With this approach I know on which commit the image is based on.
