Support patching when image container is in a deeper node

[adusumillipraveen]

I am trying to use kubeyaml with kustomize manifest generation in flux. It works great in most of my scenarios except for the cases when the image node is deep in values . It seems to be looking for image key in dicts one level inside values

apiVersion: helm.fluxcd.io/v1
kind: HelmRelease
metadata:
  name: draft-store-service
  namespace: rpe
spec:
  values:
    java:
      image: hmctspublic.azurecr.io/draft-store/service:prod-167db162 (works)
      functionaltests:
        image: hmctspublic.azurecr.io/draft-store/service-test:prod-167db162 (doesn't work) 

It would be great to support deeper paths ( flux support this and updates images in deep nodes when using patchUpdated configuration, but we cannot use it for other reasons) . Are there any alternatives to achieve this ? Happy to contribute with your guidance if it makes sense to be added here.
