Link to Team Browser from Homepage

[mtorres253]

As an 18f employee, I want to have access to the team browser so I can search for team members, or find groups of team members who match certain skill sets, or interests, so there should be a way for me to get to the team browser from the Hub homepage

Acceptance criteria
Given I am an 18f employee
When I'm viewing the homepage
Then I should see a link to the team browser
And when I click on that link, I should go to team.18f.gov

Note: this can be a link in the Recent Hires section
