There are ecp failures about disallowed image registries for the cloud bootc container images. See https://konflux.apps.stone-prod-p02.hjvn.p1.openshiftapps.com/application-pipeline/workspaces/rhel-ai/applications/nvidia-gcp-bootc-1-3/pipelineruns/nvidia-gcp-bootc-check-ecp-prod-1-3-9fff4/logs for example. 

Reason: Base image "registry.stage.redhat.io/rhelai1/bootc-nvidia-rhel9" is from a disallowed registry

Goal: 

• Update the ECP rules to allow this container registry for all bootc cloud container images

Acceptance Criteria:

• The error is no longer present when building bootc cloud container images
