ReadMe Enhancement: Installation and Usage

[RatulMaharaj]

Hi there! 👋

This project is a so cool, thank you for making it available!

This was my first interaction with a web component, and I struggled a tiny bit to figure out how to install and use the @dotlottie/player-component until I found the npm package.

Just wanted to suggest adding the Installation and Usage guidelines that's already on npm to the github readme as well. I think it could be extremely helpful 💡

Edit: I see now that there are already readme files at a package level. Maybe just a link to those from the main readme would probably work as well :)
