 The code below creates a "Hello, world!" issue on every repository in a given organization. Without the throttling plugin it would send many requests in parallel and would hit rate limits very quickly. But the `@octokit/plugin-throttling` slows down your requests according to the official guidelines, so you don't get blocked before your quota is exhausted.
 
 The `throttle.onSecondaryRateLimit` and `throttle.onRateLimit` options are required. Return `true` to automatically retry the request after `retryAfter` seconds.
