qdoc: Don't end sentences with a full stop in requisite tables

This is a minor visual change that stops QDoc from ending the
sentences with a full stop in the tables for class/QML type
requisites (Inherits, Inherited by, etc).

This ensures a uniform look for the table, as some of the
fields were already omitting the full stop.
