I'm using ArgoCD from OperatorHub in a private/air-gapped environment and need to know which images should be synced to my private registry. This information should be defined in the relatedImages section of the CSV (ClusterServiceVersion), but the ArgoCD operator currently lacks this definition.

This makes it challenging to:

1. Identify all required images for air-gapped installations
2. Ensure all necessary images are mirrored to private registries
3. Deploy ArgoCD operator reliably in disconnected environments

Could we add the missing relatedImages section to properly document all required images for the ArgoCD operator?

This would help users in private/air-gapped environments to properly prepare their environments for ArgoCD deployment.
