Model/View Tutorial and Model/View Programming examples are mixed language / bad syntax

These two documents appear to be very important, but the generated code examples end up being a mix of C++ and python, or missing critical information.

https://doc.qt.io/qtforpython/overviews/model-view-programming.html#model-view-programming

They both seem to break in a similar place, which can be found by searching for Q_OBJECT in the page. From there forward the code examples tend to be unusable.

Seems directly related to explanation in PYSIDE-1952.

I have found more of these as I read through the PySide6 docs, if there's something specific you'd like me to do with the other issues, please let me know
