Create Gist section on site

[Wotuu]

The Gist section will be a separate section in the top header (if there's space? maybe some reworking required?)

When opened, the page will display an overview page like you would when opening the routes season overview page (https://keystone.guru/routes/tww/season/1). You can then open gists filtered by dungeon. The thumbnails would also need to be zoomed in to the location that the user wanted to be zoomed in for.

Below this would be a list of popular gists I guess, based on a similar approach as the current way of deciding what is popular and what's not.
