Try storybook/addon-react-native-web with Chromatic for easier visual regression testing

[siepra]

There's a https://storybook.js.org/addons/@storybook/addon-react-native-web tool which helps you use storybook for mobile the same way as the web one.

We're particularly interested in the possibility to use Chromatic for visual regression testing of our mobile components, which may be possible with the use of the mentioned tool.

I've spent a few hours on it without success. The tricky thing is we cannot simply execute sb init command due to lerna usage that doesn't allow to install packages using npm command directly.

Also it seems keeping @storybook/react-native along with @storybook/react-native-web introduces extra complexity.

I think it's worth coming back to it when those packages become more mature of if we ever stop using lerna.

This doesn't seem urgent so I'm moving it to backlog
