Add button to the Services Directory Page

[rosy1280]

Currently the services directory lacks a way of linking to the page that it references. See the pattern library screenshot below:

The original designs by Viget show that there should be a button below the description. See the Figma screenshot below:

Update the Pattern Library according to the following acceptance criteria:

• [ ] Include the Button Form atom
• [ ] The button form item should appear below the description text.
• [ ] When the collapsed area unfurls, the button should also appear, it should not appear before then.

The button is fixed, deployed, and available for review. http://template.library.emory.edu/styleguide/patternlibrary/current/?p=templates-service-directory
