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"
 })
