Description of problem:

Red Hat documentation for the applications in non-control plane namespaces as fpund in the GitOps 1.7.0 release notes are inaccurate (specifically the disclaimer) and should be updated

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

1. see docs at https://docs.openshift.com/container-platform/4.11/cicd/gitops/gitops-release-notes.html#new-features-1-7-0_gitops-release-notes  
   see disclaimer right above fixed issues (https://docs.openshift.com/container-platform/4.11/cicd/gitops/gitops-release-notes.html#fixed-issues-1-7-0_gitops-release-notes)

Actual results:

Current docs read:

"With this update, applications can be created in any namespace in the same cluster and still managed by the same control-plane’s ArgoCD instance. This is done by adding a new label argocd.argoproj.io/managed-by-cluster-argocd to the namespace added in spec.sourceNamespaces of the Argo CD custom resource."

The disclaimer that follows reads:
"

"

Expected results:

Some corrections:

users don't need to apply the " argocd.argoproj.io/managed-by-cluster-argocd" label to a namespace themselves. This is handled by the operator.

Admins need to add the namespace to `.spec.sourceNamespaces` for a cluster-scoped Argo CD instance that will manage the application. Admins also need to add this namespace to `.spec.sourceNamespaces` of the AppProject that is associated with the application 

The disclaimer should instead read
"Argo CD Applications in non-control plane namespaces is a Technology Preview feature only"

Cherrypicking failed for enterprise-4.10 branch. This is why we needed to manually cherrypick the content into enterprise-4.10
