I did a general search and found that the health check code in the book, here

kubebuilder/docs/book/src/multiversion-tutorial/testdata/project/main.go

Lines 122 to 126 in 948887a

	if err := mgr.AddHealthzCheck("health", healthz.Ping); err != nil {
	setupLog.Error(err, "unable to set up health check")
	os.Exit(1)
	}
	if err := mgr.AddReadyzCheck("check", healthz.Ping); err != nil {

may also be updated to use healthz and readyz.
