The `Bun.sleep` method provides a convenient way to create a void `Promise` that resolves in a fixed number of milliseconds.
```ts
// sleep for 1 second
await Bun.sleep(1000);
```

Internally, this is equivalent to the following snippet that uses [`setTimeout`](https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setTimeout).
```ts
await new Promise(resolve => setTimeout(resolve, ms));
```
