feat: allow image to be overridden for the Image Updater integration - #1310

the default value is a bit confusing. For this field, the default is "", quay.io image as a fallback default is applied in the code not in this field. How about:
| Image | [Empty] | The container image for Image Updater. Takes precedence over the `ARGOCD_IMAGE_UPDATER_IMAGE` environment variable; when both are unset, defaults to the stable Image Updater image at quay.io for this version of OpenShift GitOps. |
I perfer to avoid referring to specific image updater version here, which can easily get out of sync.

how about removing this subtest? We'll need to remember to update it every time we update image updater version. If we forget to update the constant DefaultImageUpdaterTag, this subtest will still pass, giving false positive.

Assert the CR image in the generated Deployment.
TestSelectImageUpdaterImage tests the selector directly, but it does not test reconcileImageUpdaterDeployment. The deployment test uses an empty .Spec.ImageUpdater.Image and therefore cannot detect a regression where the Deployment ignores the selector or fails to propagate a CR override.
Suggested fix
a := makeTestArgoCD(func(a *argoproj.ArgoCD) {
a.Spec.ImageUpdater.Enabled = true
+ a.Spec.ImageUpdater.Image = "my-registry.io/custom-image-updater:custom-tag"

What does this PR do / why we need it:
The Image Updater integration should allow users to override the container image being used to run the Image Updater by introducing a new field .spec.imageUpdater.image, in alignment with other components of the Operator.
