kf6-syntax-highlighting: add version 6.2.0

KDE Frameworks 6 syntax-highlighting.

This is a stand-alone implementation of the Kate syntax highlighting engine.
It's meant as a building block for text editors as well as for simple
highlighted text rendering (e.g. as HTML), supporting both integration with a
custom editor as well as a ready-to-use QSyntaxHighlighter sub-class.
