What is the URL of the document?

https://sdk.operatorframework.io/docs/building-operators/golang/operator-scope/#watching-resources-in-a-set-of-namespaces

Which section(s) is the issue in?

Watching resources in a set of Namespaces

What needs fixing?

MultiNamespacedCacheBuilder is deprecated and removed since controller-runtiime v0.16.0 . It would be great if the example is updated using cache.Options.Namespace instead.

NewCache: func(config *rest.Config, opts cache.Options) (cache.Cache, error) {
	opts.DefaultNamespaces = map[string]cache.Config{
		"my-ns": cache.Config{},
	}
	return cache.New(config, opts)
},
