CLI 8.2.x does not respect the targetSdk from AndroidManifest.xml

Issue Description

After we upgraded to {N} 8.2.2 we found that during build, the CLI sets the targetSdk to 31 instead of respecting the value in App_Resources/Android/src/main/AndroidManifest.xml which was in our case set to 30.

The merged, final manifest in the APK has targetSdk 31

This is read from platforms/android/gradle.properties, defined as NS_DEFAULT_COMPILE_SDK_VERSION=31, applied in the platforms/android/app/build.gradle file through

def computeTargetSdkVersion = { -> project.hasProperty("targetSdk") ? targetSdk : NS_DEFAULT_COMPILE_SDK_VERSION as int }

Workaround: specify targetSdk in the config/android/resources/gradle.properties, e.g.

targetSdk = 30

Reproduction

in App_Resources/Android/src/main/AndroidManifest.xml set

<uses-sdk
    android:minSdkVersion="26"
    android:targetSdkVersion="30"/>

run ns build android

check platforms/android/app/build/intermediates/manifest_merge_blame_file/debug/manifest-merger-blame-debug-report.txt or check the generated APK and it's embedded AndroidManifest.

Relevant log output (if applicable)

from `platforms/android/app/build/intermediates/manifest_merge_blame_file/debug/manifest-merger-blame-debug-report.txt`

Kiểm tra platforms/android/gradle.properties và platforms/android/app/build.gradle, tập trung vào computeTargetSdkVersion. Tái hiện với App_Resources/Android/src/main/AndroidManifest.xml và ns build android, sau đó kiểm tra báo cáo manifest-merger-blame hoặc APK đã tạo. Được xem là hoàn tất khi targetSdkVersion 30 trong manifest vẫn là 30 thay vì trở thành 31.
