fix(wrangler): Fix `pages dev` watch mode [_worker.js]

[CarmenPopoviciu]

What this PR solves / how to test

The watch mode in pages dev for Advanced Mode projects is currently partially broken, as it only watches for changes in the _worker.js file, but not for changes in any of its imported dependencies. This means that given the following _worker.js file

import { graham } from "./graham-the-dog";
export default {
    fetch(request, env) {
    return new Response(graham)
    }
}

pages dev will reload for any changes in the _worker.js file itself, but not for any changes in graham-the-dog.js, which is its dependency.

Similarly, pages dev will not reload for any changes in non-JS module imports, such as wasm/html/binary module imports.

This commit addresses all the aforementioned issues.

Fixes #4824
