Make the whole card clickable (including the image) for featured projects

Feature suggestion

The featured projects cards on the home page are only clickable from the text header (e.g. "Easy-to-use campaign data") and the "Read more >" link. Most of the time, people expect the image and entire card to be clickable to take them to the link. It'd be great if we could update these so that you can select anywhere on the card to go to the link.

User story

As a user, I want to be able to click on the image so I can get to where I need to go.
