QSyntaxHighlighter documentation still using QRegExp (instead of QRegularExpression)

The coding examples for QSyntaxHighlighter (http://doc.qt.io/qt-5/qsyntaxhighlighter.html) are still using the old QRegExp although it says in the documentation also that from Qt5 on QRegularExpression should be used.

This of course leads new users to use the slower and unmaintaned QRegExp implementation.
