hack: Update to using kube_codegen.sh instead of generate-groups.sh

We are getting the following warnings if we continue using generate-groups.sh
so updating to kube_codegen.sh instead as per the recommendation:

```
WARNING: generate-groups.sh is deprecated.
WARNING: Please use k8s.io/code-generator/kube_codegen.sh instead.
```
