method StatWatcher.unref
Usage in Deno
```typescript import { type StatWatcher } from "node:node__fs.d.ts"; ```
StatWatcher.unref(): this
When called, the active `fs.StatWatcher` object will not require the Node.js
event loop to remain active. If there is no other activity keeping the
event loop running, the process may exit before the `fs.StatWatcher` object's
callback is invoked. Calling `watcher.unref()` multiple times will have
no effect.
