 * const exampleNamespace = new azure.eventgrid.Namespace("example", {
 *     name: "my-eventgrid-namespace",
 *     location: example.location,
 *     resourceGroupName: example.name,
 * });
 * const exampleNamespaceTopic = new azure.eventgrid.NamespaceTopic("example", {
 *     name: "topic-namespace-example",
