Update kyaml/kustomize api versions to current versions in catalog functions. #4406
Description
Currently, a lot of functions in the catalog use severely outdated versions of kyaml and kustomize api. Updating the versions also requires rewriting some of the logic because of API changes. This also means that these functions will require at least a minor version bump, but probably a major would be fitting as well.
Current targets should be:
- kustomize api and kyaml >= v0.21
- k8s api and apimachinery >= v0.35
- k8s yaml >= 1.6
- probably update testify to >= v1.11 as well
