thanks to @msz for idea and execution steps.
This commit takes the existing recent-articles.html partial
from themes/congo/layout/partials and copies it to override
the theme partial. Instead of listing 'Site.RegularPages' that
match the configured content in the 'mainSections'
configuration, it takes the more general Site.Pages, which
would allow listing Term Pages (see
https://gohugo.io/quick-reference/glossary/#term-page).
disable recent section in configuration
At its current state, it is not polished enough to enable it
The 'Recent' section would show the content/samples files,
pointing to documentation and other boilerplate content.
I've replaced this config according to
https://jpanther.github.io/congo/docs/homepage-layout/#recent-articles.
I've also adjusted the description to something non-hugo related (the
first sentence of the current website) as an interim improved
description
