The documentation platform needs a better way of generating navigation

[jobara]

Currently navigation in the documentation platform is a manual process. site-structure.json defines the structure with groupings, titles, and URLs. This structure is very fragile because:

1. If the titles do not match the titles in the documents, an active indicator will not appear in the sidebar navigation.
2. If the URL is incorrect in the site-structure.json file, you will no know there is a problem until manually encountered.

A more robust or automatic method of generating navigation should be used. Consider using 11ty's navigation and/or collections.

@jobara I might be able to look at this in August.

That'd be great. I was thinking it might make sense along side an update to 11ty 3.0 but it could happen earlier too.
