Consider renaming the Robot Arm documentation in QDS docs

The Robot Arm tutorial (https://doc.qt.io/qtdesignstudio/robotarm-example.html) is now titled "Creating a C++ Backend for a Qt Design Studio Application" and as "Robot Arm Tutorial" in the QDS Examples tab. This might confuse our users. Can we make the connection between these two clearer somehow? Maybe add the 'robot' hand' to the title somehow?

We should also go through the text to make sure it is inline with our other examples/tutorials and MS Style guide.
