Updated Readme (#52)

The following ergonomic changes were made :
1. yarn install is the command used to install dependencies not simply yarn. This was modified.
2. Added the link for the demo which was not present earlier.
3. I couldn't help but notice that there were several subject-verb agreement related grammatical errors. Fixed it.

 A fully customizable React component for copying email from `mailto` links.
 
 ## Motivation

Most of the time we just want to copy the email address and that's where this module comes into play. Big shout out to [Kuldar](https://twitter.com/kkuldar) whose tweet [thread](https://twitter.com/kkuldar/status/1270736717939716097) inspired us to build this.
