v2.4.0

This fixes https://github.com/master-atul/react-native-appstore-version-checker/issues/8

Nothing to do . Just upgrade the package and use it
the default way

getAppstoreAppVersion('com.supercell.clashofclans') //put any apps packageId here
.then((appVersion) => {
  console.log('clashofclans android app version on playstore', appVersion);
})
.catch((err) => {
  console.log('error occurred', err);
});```
