Deprecated API usage notice on Android

[piotr-cz]

Describe the bug

When building app in Android Studio, following notice is printed in the Build tab:

> Task :capacitor-community-apple-sign-in:compileDebugJavaWithJavac
Note: XXX\node_modules\@capacitor-community\apple-sign-in\android\src\main\java\com\getcapacitor\community\applesignin\SignInWithApple.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

> Task :capacitor-community-apple-sign-in:bundleLibCompileToJarDebug

To Reproduce
Steps to reproduce the behavior:

Additional context

I'd say that the src/main/java/com/getcapacitor/community/applesignin/SignInWithApple.java file was omitted from upgrades when rest of plugin code base was upgraded to Capacitor 4 and Capacitor 5
