Change is it awesome link to twitter followers

What does this MR do and why?

Change the link for Is it awesome to https://twitter.com/gitlab/followers from https://twitter.com/gitlab/likes. https://twitter.com/gitlab/likes shows the tweets liked by the GitLab account and not the people who like GitLab. https://twitter.com/gitlab/followers is a better representation of people who actually like GitLab.
