There have been a lot of changes in 5.74, especially on the parts you are talking about. Unfortunately, your version (5.70) does not allow you to retrieve the last version of the file, but you can copy https://invent.kde.org/frameworks/syntax-highlighting/-/blob/9c4b385d6843d23713f478f73e98994ba41ce1f3/data/syntax/scheme.xml in ~/.local/share/org.kde.syntax-highlighting/syntax (you must create the folder if it does not exist).
