After updating Red Hat OpenShift GitOps Operator in the "latest" Updatechannel to version 1.6.0, Customer has discovered that repositories were deleted in the custom ("not GitOps") ArgoCD instances.

Additional Info : 

• Customer observing issue with repositories in ArgoCD (Settings -> Repositories)
• The information about the repositories is saved in secrets.
• In this secrets every information (e.g. the url) getting deleted except the username and password. 
  Note : secrets managed by GitOps
• The secrets are changed and the information "project, url, namespace" are missing. 
  Because of that the repositories are "deleted"/missing in the GitOps Operator. 
  This doesn't hit every  repository but the most. In some cases are all repos gone. 
• Operator updated from 1.5.5 via the OperatorHub.
