Describe the issue

As of v1.33, Kubernetes supports declarative validation for API developers.

• https://kubernetes.io/docs/reference/using-api/declarative-validation/

The kubernetes/community documentation at:

• contributors/devel/sig-architecture/api_changes.md
• contributors/devel/sig-architecture/api-conventions.md

should be updated to reference declarative validation where appropriate, explain that it is the preferred way to declare validation of types and fields for supported validations, and explain how to use it generally.
