fix(android): update path of newarch generated classes

[aladine]

The path generation in Android assuming developer always run this command to generate source code during prebuild:

./gradlew generateCodegenArtifactsFromSchema

However, for my project, the outputDir in codegenConfig is not respect correctly. This happens probably due to gradle or AGP version. When I change to project.buildDir absolute path, the Android build is working for new architecture.
