Suggestion: Extend the Quick start guide to importing a new project

[Jacob-purplerock]

Hello,

The "Quick Start" page currently ends at the point where QWC2 (either standalone or docker) is running. It would be valuable to extend the quick start guide to the point where a new project is loaded into qwc2 and viewed. Perhaps working from the sample created by some other documentation like this qgis page

As-is, the documentation is very unclear about how to get data other than the included demo viewable in qwc2 without already having an extensive knowledge base. This would be a good bridge between the existing quick start guide and the detailed documentation that follows.

There is certainly room for improvement here, contributions very welcome!
