Small adjustments in support of unified docs site

[mlr]

These are some small adjustments made in support of the unified docs site build.

1. Style inline code blocks within summary titles
Before (top) / After (bottom)

2. Style external nav content anchors the same as xhref anchors
Before (left) / After (right)

3. Render navigation when single list structure is used

Prior to this change the nav tree would be unrendered / blank.
We have a very large amount of doc sites that use an Antora single list structure so this change facilitates rendering those nav structures without manual edits. Over time we can move toward a top level item for every link. This is what the streaming docs site looks like with this change (prior the nav did not render).

Nice bug fix! (Sometime in the future we should do an overall design pass on all the various types of block titles.)

2. Style external nav content anchors the same as xhref anchors Before (left) / After (right)

I can't remember if @colegoldsmith already investigated this, but it would be nice if the automatic external link styling also applied to external links in the nav, i.e. add the external icon.

Yeah, I think the rule should be if there are no list titles in the nav, everything should get promoted up a level.

Happy to look into this in a follow up PR, the changes in this PR are going to apply for any link (external or not) in the nav that is not an xhref

Looks good!
