frontend: KubeObject: Refactor getAuthorization logic

This change updates the logic of the getAuthorization function in
KubeObject, which previously intended to test auth by separating the
group from its respective version when one of these was missing. Now,
these two fields are linked and grabbed together from apiInfo when one
is missing.

Fixes: #2633
