• Issue Description: The CI job failed during the dynamic plugin installation step due to an inability to download the plugin catalog index image from the Red Hat Registry.
• Failure Details: The installation script failed with a fatal error: initializing source }}{{{}[docker://registry.redhat.io/rhdh/plugin-catalog-index@sha256:e2536de5fb14d92681862fa7e57f2e06cce2ebdc3a1f3c35cd9724d819833d6a]: unable to retrieve auth token: invalid username/password: unauthorized: Please login to the Red Hat Registry using your Customer Portal credentials.
• Root Cause Analysis: The root cause of the failure is an authentication error with the Red Hat Registry (registry.redhat.io). The process attempting to pull the plugin catalog image lacks valid credentials, leading to an unauthorized error. This indicates that the required pull secret for registry.redhat.io is either missing, misconfigured, or contains invalid/expired credentials within the CI environment.
• Actionable Recommendations:
  1. Ensure a valid pull secret with credentials for registry.redhat.io is created in the showcase namespace where the deployment is running.
  2. Verify that the service account executing the pod has the correct pull secret attached to it, allowing it to authenticate with and pull images from the Red Hat Registry.
