Render a more test case-centric report

[davidjgoss]

🤔 What's changed?

Change the way documents are rendered to be more test case centric. The main effect is:

• Backgrounds are not shown separately but are inlined to each test case
• Templated scenarios list each compiled pickle/test case separately, not as examples tables

⚡️ What's your motivation?
