Describe the bug

When a user uses the CLI to restart deployments via an action, the CLI fails to discover and restart Deployments that are not present in Git -- such as Deployments created by an external operator.

This is presumably because the CLI is using managed resources (git) instead of the resource tree (git + children):

https://github.com/argoproj/argo-cd/blob/b39ca155dc325b14c246be7b50d49518887d9523/cmd/argocd/commands/app_actions.go#L179

To Reproduce

• Find a Deployment that is created by an external operator and that is not defined in git
• Use the CLI to restart all deployments in the namespace

argocd app actions run $appName restart --kind Deployment --all

• See that these Deployments are not restarted

Expected behavior

All Deployments are restarted; regardless if they are present in git or not.
