reference assignment name in arialabels in list view

fixes CNVS-22932

- Update the PublishIconView instantiated by AssignmentListItemView to
  provide cusom publishText & unpublishText that includes the
  assignment's name.
- Update edit, delete & move links in the AssignmentListItem view to
  reference assignment's name.

test plan:
- Using NVDA, navigate the publish, edit, delete & move controls from
  the assignment list view and validate that the assignment name is
  included along with other text.
