Add annotations for ApplicationSet

      annotations:
        argocd-image-updater.argoproj.io/image-list: "myimage=myecrrepo/app-podinfo:test"
        argocd-image-updater.argoproj.io/myimage.update-strategy: digest
        argocd-image-updater.argoproj.io/myimage.force-update: "true"
        argocd-image-updater.argoproj.io/myimage.helm.image-name: image.repository
        argocd-image-updater.argoproj.io/myimage.helm.image-tag: image.tag
        argocd-image-updater.argoproj.io/write-back-method: git
        argocd-image-updater.argoproj.io/write-back-target: "helmvalues:./../values.yaml"

and my values.yaml is

skipDeploy: "false"

containerPort: 9898

image:
  repository: myecrrepo/app-podinfo
  tag: test

container:
  command:

Expected behavior

change image.tag
