[ANDROID] NDK Version Mismatch

Description

Since we recently upgraded AGP to 9. The default version of ndk is now 28.2.13676358 . However RN template still ships with 27.1.12297006. I am not sure if this was intentional .

This is fine for most of the apps . But the issue comes with cpp libraries who have not defined NDK Version explicitly in their android/build.gradle. This is causing some libraries to compile with different NDK Version and crashes on startup with below error

For example
Here we can notice both 27 and 28 ndk

When I specifically define NDK 27 in android/build.gradle of my library . The issue is fixed

I can see two solutions for this

1. Either we can ask library to ship ndk version default. I checked in CRNL . They also dont ship currently. So maybe adding in template of CRNL and nitro
2. Upgrading app template and RNGP to use 28.x.x

Steps to reproduce

1. Install the Repro
2. Run the example app
3. It will crash

4. Add ndkVersion getExtOrDefault("ndkVersion") to the android of the library it will be fixed

Screenshots and Videos

まず、必須の例で発生するクラッシュを再現し、React Native template とネイティブライブラリで使用されている NDK のバージョンを比較します。テンプレートの Android 設定、RNGP、および参照されている react-native-builder-bob native-common/android/build.gradle を調査します。サポートされる NDK の動作を明らかにし、バージョンの不一致が原因で例がクラッシュしなくなるよう、関連するテンプレートまたはライブラリのガイダンスを更新できれば完了です。
