Change repository description from plain text to remarkup

Summary:
At one point this was sort of a one-line summary but it isn't really anymore (and doesn't appear on the list view). We could add a summary in the future if we wanted.

  - Change the control from a text area to a remarkup area.
  - Change the display to remarkup.

Test Plan:
{F44183}
{F44184}
