What does this change?

문제

현재 @react-native-kakao/core의 Expo config plugin은 AndroidManifest에
아무 속성도 없는 <activity/> 태그를 삽입합니다.

<activity/>

이로 인해 :app:processDebugMainManifest 단계에서
Missing 'name' key attribute on element activity 오류가 발생하며
Android 빌드가 실패합니다.

수정

• 불필요한 dummy activity 삽입 코드를 제거했습니다.
