Wrong servlet urlPattern on SignInStatusServlet

### 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)

The servlet urlPattern should be "auth_sign_in_status" not "sign_in_status" since the pattern is always to start with "auth_" and is declared in token.jsp

### Which sample?
ms-identity-msal-java-samples/3-java-servlet-web-app/1-Authentication/sign-in-b2c/src/main/java/com/microsoft/azuresamples/authenticationb2c/SignInStatusServlet.java

### Minimal steps to reproduce
>
Go to auth_token_details page and click on Sing-In Status

### Expected/desired behavior
>
Go to auth_sign_in_status

### OS and Version?
>
Linux

### Versions
>
Ubuntu 22.04.3 LTS

Öffne 3-java-servlet-web-app/1-Authentication/sign-in-b2c/src/main/java/com/microsoft/azuresamples/authenticationb2c/SignInStatusServlet.java und vergleiche das URL-Muster des Servlets mit der Referenz in token.jsp. Überprüfe den Sign-in-Status-Link aus auth_token_details und bestätige, dass er zu auth_sign_in_status aufgelöst wird.
