Direct side feedback mechanism

[thibaudcolas]

Part of recommendations from user research report in #1496

Recommendations

Implement a feedback system directly on the website, allowing users to report problems or suggest improvements as they browse.

And:

The idea of actively engaging the community through up-to-date information and tools such as surveys, feedback directly on the site, and the ability to evaluate the usefulness of pages could provide a channel for obtaining direct opinions from users and continuously improving the site.

Working on this

Start by reviewing the feasibility of this. Possibly this could be as simple as using GitHub Discussions – create a Discussions thread per page of the site, link to it at the bottom of the pages? Similar to Giscus but without the "on-page commenting" aspect.
