[Feature] - Documentation Website

[fabOnReact]

Creating a website with the documentation for this project. Feel free to build it like you want it.

Some notes:

• The iOS library for developing Watch Apps https://github.com/mtford90/react-native-watch-connectivity
• Their documentation https://mtford.co.uk/projects/react-native-watch-connectivity/docs/
• The GitHub repo of the documentation website https://github.com/mtford90/react-native-watch-connectivity.github.io

The website could be the documentation for both react-native-watch-connectivity (iOS) and react-native-wear-connectivity (Android) (but also other libraries).
