Pale color for definition terms at docs.rtems.org

[Sebastian Huber]

Hello,

after the Sphinx update I think the color of the definition terms is 
quite pale:

https://docs.rtems.org/branches/master/c-user/event_manager.html#directives

Removing the "dt" stuff from my-style.css seems to fix the problem. 
However, I have absolutely no idea what I changed and what this stuff is 
supposed to do.
