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

### Which sample?

Java Spring WebAPI II

### Minimal steps to reproduce
The [comment in this file ](https://github.com/Azure-Samples/ms-identity-msal-java-samples/blob/main/4.%20Spring%20Framework%20Web%20App%20Tutorial/3-Authorization-II/protect-web-api/resource-api/src/main/resources/application.yml)is correct but the last line is incorrectly suggesting that the same value (guid) as enter for client-id should be used for app uri. In AAD app-uri may be different to the client id, e.g. appi://myapi is valid. The hint should be replaced to say Enter_your_app_uri_here.

### Any log messages given by the failure

### Expected/desired behavior
>The hint should be replaced to say:
app-id-uri: Enter_Your_App_Uri_Here

### OS and Version?

### Versions

Abre Open 4. Spring Framework Web App Tutorial/3-Authorization-II/protect-web-api/resource-api/src/main/resources/application.yml e inspecciona el comentario de app-id-uri. Actualiza la indicación para que use un marcador de posición de app URI en lugar de dar a entender que es el client ID; después, verifica que la configuración de ejemplo siga distinguiendo la app URI del client ID.
