Fix Metro preset version (#21034)
Fix Metro preset version (#21034)

Summary: This pull request removes the hard-coded version of the `metro-react-native-babel-preset` as defined in the `init` command. That way, the version always matches React Native version specified in its `package.json`, making it match Metro version.
