`Kustomization` file missing `.yaml` at the end

Kubernetes recommends naming the `kustomization` file as `kustomization.yaml` https://kubernetes.io/docs/tasks/manage-kubernetes-objects/kustomization/, and [argoCD also requires the same ](https://argo-cd.readthedocs.io/en/stable/user-guide/kustomize/)in order for it to be able to use `kustomize` resources.

With the current name, argocd fails to pick up the `kustomization` file as well.

Can we please go ahead and rename the file to `kustomization.yaml` as per recommendations by kubernetes, and argoCD?
