Following README instructions do not result in running app locally

### This issue is for a: (mark with an `x`)
```
- [x ] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)
```

### Minimal steps to reproduce
> Clone repo and follow README ## Before running the sample for the first time

### Any log messages given by the failure
> No failure in the console, but browser does not open the web app

### Expected/desired behavior
>When the browser is opened, the app is loaded

### OS and Version?
> Windows 11

### Versions
> Edge latest version

### Mention any other details that might be useful
Couple things that are suspicious:

Package.json
- "start-local": "webpack-dev-server --port 5000 --mode development",
- "start": "webpack-dev-server --host 0.0.0.0",
README
- 7. Open localhost:5000 in a browser. (Supported browsers are Chrome, Edge Chromium, and Safari)
- Deployment to Azure mentions, but it is not in the first section
- - "start-local" script. This will start the server on local machine at port 5000.
webpack.config.js
- const PORT = process.env.port || 8080;

So is it localhost/0.0.0.0 and 5000/8080 port? Can someone update the code/config/readme to make it work for local deployment?

Inizia riproducendo su Windows 11 i passaggi di “Before running the sample for the first time” del README, quindi confronta gli script start-local e start in package.json con le impostazioni di porta e host in webpack.config.js. Conferma a quale URL locale il server di sviluppo serve l’applicazione e aggiorna il workflow documentato in modo che, seguendolo, l’app si apra correttamente.
