 The following example creates a `Gateway` named `example-gateway` in namespace `gateway-namespace` (lines 2-4). The gateway has a `certificateRef` in namespace `secret-namespace` (lines 16-18). The reference is allowed because the `ReferenceGrant` configuration, named `reference-grant` in namespace `secret-namespace` (lines 23-26), allows `Gateways` in `gateway-namespace` to reference `Secrets` in `secret-namespace` (lines 30-34).
