feat(): add error handling when remote is down

[infoxicator]

When app2 is down the entire app crashes. Since the route definition is synchronous and happens before the app renders, we can't do a dynamic import like const routes = await import('app2/routes') in order to catch the error so it has to be caught before the module federation promise rejects.

I found another alternative where you can create a promise chain and resolve before the app i.e.

import('app2/routes').then(async (module) => {
    ReactDOM.render(<App routes={module.default} />, document.querySelector('#root'));
  }).catch(e => { 
// handle error or render App with fallback routes
}

But it would be great to have an example on how to use the low level API above to handle this on the script.onerror()
