Deprecated structure in appinsts.yml

[Mulinho]

The example presented below (from appinst.yml) does not work with mobiledgex/deploy-app-action@v1.2.2.

- appinst:
    key:
      cluster_inst_key:
        cluster_key:
          name: venky-test
        cloudlet_key:
          name: frankfurt-main
          organization: TDG
        organization: VenkyDev

This structure should work:

- appinst:
    key:
      cluster_inst_key:
        cluster_key:
          name: venky-test
          organization: VenkyDev
        cloudlet_key:
          name: frankfurt-main
          organization: TDG
