fix: app tree parentRef response missing version info

[hanxiaop]

Currently, the application tree response is missing the version in the ParentRef. This is inconsistent with other usages of the same ResourceRef structure and also inconsistent with the appset tree , which includes the version:

argo-cd/server/applicationset/applicationset.go

Lines 399 to 401 in 31e8ff8

	parentRefs := []v1alpha1.ResourceRef{
	{Group: gvk.Group, Version: gvk.Version, Kind: gvk.Kind, Name: a.Name, Namespace: a.Namespace, UID: string(a.UID)},
	}

Adding this would be helpful for directly comparing the ParentRef with the resourceRef.
