### 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
>

### Mention any other details that might be useful

Öffne Open 4. Spring Framework Web App Tutorial/3-Authorization-II/protect-web-api/resource-api/src/main/resources/application.yml und überprüfe den Kommentar zu app-id-uri. Aktualisiere den Hinweis so, dass er einen Platzhalter für die app URI verwendet, statt die client ID nahezulegen, und verifiziere anschließend, dass die Beispielkonfiguration weiterhin die app URI von der client ID unterscheidet.
