Heading links hierarchy plugin for table of contents (compatible with all template syntax)

[zachleat]

Creates a hierarchical tree of links representing the headings inside of <main> (or configurable target context)

For further UI, this could be enhanced with decoupled web component to highlight the currently visible sections, e.g. https://www.markdownguide.org/basic-syntax/#overview (though I’d like it better if it highlighted all of the visible sections, not just the one at the top of the viewport)

Works best with #3363 (maybe requires it?)

The Eleventy docs has been using https://www.npmjs.com/package/markdown-it-table-of-contents with success for awhile but it’s markdown-only.

Noting the issue (likely with plugin ordering) in the Id Attribute plugin: #3363 (comment)

I’d also note that doing #3714 first might be a better path forward for existing community plugins to use.
