Better posts on Mastodon

Currently, Feed2Toot https://feed2toot.readthedocs.io/en/latest/ posts new listings and blog posts to Mastodon.

As https://toot.io/@justin/111894483883675307 points out, it would be nice to have some description (either from the summary (= description = "") or the actual description).

At first glance, only description is possible (ATOM feed element content), but... it does not turn out well: https://linuxrocks.online/@linuxphoneapps/111897694031337618

Likely solution:

Extend feed template https://framagit.org/linuxphoneapps/linuxphoneapps.frama.io/-/blob/main/themes/lpadoks/templates/atom.xml?ref_type=heads to contain summary information. If I understand https://www.rfc-editor.org/rfc/rfc4287#page-25 correctly, a <summary> element would do this.
