Normalize scheme for URL on Android (#21561)

Summary:
Android requires lowercase for URL scheme. This commit https://github.com/facebook/react-native/commit/d00bdb9bb8b9b11bce900689c7e28cebd2eb0807 fixed it but on React Native side.
Because it is Android specific, it should be fixed on Android side.

Android has method to normalize url scheme: https://developer.android.com/reference/android/net/Uri.html#normalizeScheme()
