Update the styles on the contributing documentation

We want to update the styles and theme on the contributing documentation site. Here is a guide on how to work on the theme and styles.

We would want to:

1. Remove the extraneous CSS
   • I had shamelessly copied the code from Netflix’s awesome pollyjs project here while setting up the site.
   • The CSS above depends on the vue.css that ships with docsify.
2. Write our own theme with docsify-themeable.
3. ~Have the Universal Nav~ (already done).
4. Fonts and colors should follow our design style guide.
5. Use larger font size similar to our main sites
