Add support for related content

[markdumay]

Problem or enhancement idea

Related content is a proven way to improve user engagement. Hugo offers the option to list this content based on date and keywords.

Proposed solution

Add the option to show related content on a single page. The related content should leverage the existing Hugo configuration. Hinode should be able to configure the amount of results (1 - 5) and the sort order (e.g. by date or title, ascending or descending). The results would be displayed as clickable cards, similar to regular list pages.
