      Used to verifiy the Git tag exists on docker/buildx repo. Since there's a
      default, this is typically not supplied by the user. When running this
      action on github.com, the default value is sufficient. When running on
      GHES, you can pass a personal access token for github.com if you are
      experiencing rate limiting.
    default: ${{ github.server_url == 'https://github.com' && github.token || '' }}
