Feature request: add option to feature articles under separate category/page

[kbdharun]

Ref. current handbook landing page https://handbook.vanillaos.org/

Allow featuring posts on a separate page (similar to how we currently have it in the handbook) or at the top by setting featured: yes parameter in the page's header.

I think a redirect would also be good. For example: handbook.vanillaos.org -> docs.vanillaos.org/collections/handbook
