Adjust styles for collapsible blocks
Asciidoctor 2 (included in Antora 3) adds built-in support for a collapsible block. This block type maps to the details/summary element in HTML. While we mostly rely on the browser to style these elements, there are some quirks that need to be addressed. Those issues are as follows:
- Nested details blocks need to be indented
- Bottom margin is missing by default
- Cursor does not default to pointer
Here are relevant commits to integrate:
