* Creates a {@link Promise} that rejects after `ms` milliseconds with an

* Reject after 100ms

* .catch(() => console.log("catch")); // will be called after 100ms

* @example
* Reject after 100ms with `"err"`
* ```ts
* rejectAfterTimeout(100, "err")
* .then(() => console.log("then")) // this will never be called
* .catch((err) => console.log(err)); // will be called after 100ms

* @param ms - the number of milliseconds to wait
