Figure out github workflow to push to docker

[bozdoz]

docker build -t cli .
docker tag cli bozdoz/wordpress-initialize:latest
docker tag cli bozdoz/wordpress-initialize:1.2.3
docker push bozdoz/wordpress-initialize:latest
docker push bozdoz/wordpress-initialize:1.2.3

Need to add an access token here to github secrets, at minimum: https://hub.docker.com/settings/security

 -     name: Login to Docker Hub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKER_HUB_USERNAME }}
          password: ${{ secrets.DOCKER_HUB_ACCESS_TOKEN }}
