Add social icons for fellows

At the moment, it only displays the fellow name and location. To help people network, we should add social icons to each of the fellow cards.

• [ ] Add LinkedIn icons to the card
• [ ] Add Twitter icons to the card
• [ ] Add Resume icons to the card
• [ ] Add GitHub icons to the card
