feat: export a list of modules for use in @storybook/react-native 6 (#122)
* feat: export a list of modules for use in @storybook/react-native 6
In @storybook/react-native version 6: the loader function passed to 'configure' should return void or an array of module exports that all contain a 'default' export. `loadStories()` just loads all the stories and `stories` is just a list of the story locations. Adding `modules` so that we can also access a list of module exports.
