[pve-devel] [PATCH pve_flutter_frontend] chore: android: update `compileSdkVersion` to 36 and update AGP version

[Shan Shaji]

Set `targetSdkVersion` and  `compileSdkVersion` to (36).
According to android docs [0] the `targetSdkVersion` should be
<= `compileSdkVersion`.

Also update the Gradle and AGP versions [1] to support the new
API level.

 The `biometric_storage` plugin works well when testing it in 
 Android 16 (Emulator). The plugins 
 (shared_preference [0], path_provider [1], url_launcher [2]) all uses 
 the compileSdkVersion version of flutter v3.29 which is less than 36. 
 Also the `flutter_inappwebview` [3] is using the compileSdkVersion (34).

 The flutter default compileSdkVersion version can be found at 
 `packages/flutter_tools/gradle/src/main/groovy/flutter.groovy` which 
 is less than 36 on v3.29. Also the above groovy script also has a 
 condition to check if the plugin `compileSdkVersion` is greater than 
 `compileSdkVersion` of the App. Flutter will throw error or 
 suggestions for fixing if the `compileSdkVersion` of plugin is 
 greater than the app `compileSdkVersion`.

 Also the API level changes are forward compatible [4], means even if 
 the plugin is compiled with the API level (35). 
 It will work with the new API level (36) as it does include changes 
 from API level 35 as well. 

 The above findings resulted in updating both the `targetSdkVersion` 
 and `compileSdkVersion` to 36.
