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.
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
