style: AndroidManifest.xml's '<application' opening tag is indented by 3 spaces instead of 4

[MrCsabaToth]

Description The generated AndroidManfiest.xml has one less space for the indentation of the <application opening tag, whereas the </application> closing tag has the proper four spaces.

Steps To Reproduce

1. very_good create flutter_app my_app
2. cd my_app/android/src/main/
3. cat AndroidManfiest.xml
4. 3rd line is the opening tag

Expected Behavior Both the opening and the closing tag would have four spaces of indentation

    </application>
</manifest>

Additional Context I'll try to craft a PR.

The Flame Game and Flutter Plugin creation is affected as well, plus the Wear app creation had a different similar (one space missing) indentation for the com.google.android.wearable.standalone meta-data tag, the PR addresses those.
