OCPBUGS-33762: Hardcode resource groups/kinds for now

Previous code used `GroupVersionKind` method on actual resources to determine group/kind strings for them, but client-go unfortunately drops `TypeMeta` on resources processed by typed client (kubernetes/client-go#1328, kubernetes/client-go#541). Fortunately we know what types we build insights for, so we can use appropriate strings from client code for groups and hardcode kinds ourselves.
