While currently those objects only get published by the kubelet for node-local resources, this could change once we also support network-attached resources. Dropping the "Node" prefix enables such a future extension. The NodeName in ResourceSlice and StructuredResourceHandle then becomes optional. The kubelet still needs to provide one and it must match its own node name, otherwise it doesn't have permission to access ResourceSlice objects.
