The e2e kustomize overlay tried to match
docker.io/library/plugin-barman-cloud but the base kustomization at
kubernetes/kustomization.yaml already transforms the bare
plugin-barman-cloud image to the GHCR name. The overlay must match
the base's output (ghcr.io/cloudnative-pg/plugin-barman-cloud-testing)
to override it.
Add comments on both sides to prevent future drift.
Broken since b7daaac (#89) changed the base kustomization's newName
from docker.io/library/plugin-barman-cloud to the GHCR image without
updating the e2e overlay.
Closes#840
