Doc: Remove background colors from simplified offline CSS

The simplified style needs to work for both light and dark themes
in Qt Creator's help system. Background and text colors are already
applied according to the active theme, this commit removes the rest
of the hardcoded element colors that do not look good with a dark
theme.
