blue-green example shows no difference between active and preview service

[danielhelfand]

After following the blue-green example README instructions, the instructions ask the user to do the following:

argocd app set blue-green -p image.tag=0.2 && argocd app sync blue-green

This command is supposed to cause both versions of the guestbook app to be deployed at the same time (i.e. tags 0.1 and 0.2). Instead, both the active service (blue-green-helm-guestbook) and preview service (blue-green-helm-guestbook-preview) show the updated version.

This is possibly due to this example being out of date with rollouts changes.
