The previous commit for configuration APIs has some nits to fix:
- The client-authentication API has both v1beta1 and v1 supported.
We need to include both.
- The kube-scheduler v1alpha1 is superceded by v1alpha3 which is new.
- The links to some external type definitions should point to the 1.23
API rather than old versions.
This is a reference for WebhookAdmission config generated from kubernetes-sigs/reference-docs/genref tool.
More specifically, it is generated using the following command:
```shell
./genref -include apiserver-webhookadmission
```
