react-native-ratings shouldn't be a dependency

[geraintwhite]

Having react-native-ratings: "^6.5.0" in the dependencies and react-native-ratings: "^4.1.0" in the peer dependencies means this library uses an older version which doesn't support the latest features and props.

It would be better to omit it from dependencies and have a more flexible version like >=4, otherwise the workaround for app developers is to use the npm overrides feature with "react-native-ratings": "$react-native-ratings" to force the same version throughout.
