Refactor Monaco editor worker configuration example to use arrow functions

**Problem/Feature Description**
In the Monaco editor configuration samples/examples, the `getWorkerUrl` function currently uses the traditional ES5 function expression syntax.

**Proposed Solution**
Update the `getWorkerUrl` definition in the documentation/example snippet to use modern ES6+ arrow function syntax (`(moduleId, label) => './editorWebWorkerMain.bundle.js'`) for improved readability and modern JavaScript/TypeScript standards.
