Keeping the root of the left menu with module imports

[giuliohome]

Excellent 💯👍 job, thank you so much for sharing this branch!

I just changed the line below, in my use case, where I have submenu items generated by imported hugo modules from external repositories (instead of building a monorepo)

docsy-dev-page/layouts/partials/sidebar-tree-foldable.html

Line 28 in d943e52

{{ $navRoot := cond (and (ne .Params.toc_root true) (eq .Site.Home.Type "docs")) .Site.Home .FirstSection }}

to a trivial assignment of always Home (not sure why and when it really needs to be the first section though?)
