Unable to override operator image using make deploy

[lampajr]

Describe the bug Running make deploy IMG=<some-registry>/model-registry-operator:tag as described in the README does not override the operator image by using the provided one, it keeps using the :latest.

The issue seems to be in the make deploy script, in particular: $(KUSTOMIZE) edit set image controller=${IMG} - where controller is not an image, therefore nothing is going to be replaced while issuing kustomize build

To Reproduce Steps to reproduce the behavior:

1. Run cd config/manager && kustomize edit set image controller=quay.io/opendatahub/model-registry-operator:main-4c04ff7
2. config/manager/kustomization.yaml should contain the following changes:

   apiVersion: kustomize.config.k8s.io/v1beta1
   kind: Kustomization
   images:
   - name: controller
   newName: quay.io/opendatahub/model-registry-operator
   newTag: main-4c04ff7

3. Issue kustomize build . or kustomize build config/manager depending if you are in the target directory or in the root.
4. Check the generated output still contains :latest image:

   ...
         value: "false"
       image: quay.io/opendatahub/model-registry-operator:latest
       livenessProbe:
         httpGet:
           path: /healthz
           port: 8081
   ...

Expected behavior The kustomized build should contain the overridden image: image: quay.io/opendatahub/model-registry-operator:main-4c04ff7
