fix(client): GVR core resources caching

[floreks]

GVR caching logic did not consider that there can be CRDs with the same names as the core resources in different groups. Since discovery client returns unsorted list with a randomly ordered elements, it resulted in raw client request to a different resource than expected.

Fixes #9994
