Add comprehensive documentation for resolving ArgoCD image-updater credential
errors with multi-source applications. Documents the solution of using ArgoCD
API write-back method instead of git write-back for applications that use
external Helm charts with local values repositories.
Key learnings:
- Multi-source apps need argocd write-back method not git
- External chart repos don't need write credentials with API method
- Includes step-by-step implementation and verification commands
