2021 Gitcoin Design Component Library

### User Story

As an operator of Gitcoin, we would like to ensure a cohesive, consistent experience and ensure all contributions meet brand guidelines.

As a design contributor contributing to Gitcoin, I'd like to have a template to work from so that I can stay consistent with the Gitcoin Brand guidelines.

As a developer implementing designs, I'd like to have a source of truth for reference on the css and html components so that I can easily/quickly copy and paste the styles from Figma into what I'm developing to maintain brand standards.

### Why Is this Needed

The original design components were designed in sketch and could use an update given how the brand has evolved.

### Description

Create a source of truth for Gitcoin design across marketing and product

### Definition of Done
