I've put this as large, since Eduardo's having a fair amount of trouble currently upgrading SS to Ruby 3. Hopefully we'll get some learnings from that though!

Adjusting this to small since samples extraction is already on ruby 3 at the time this has been picked up and the rails 7 upgrade was straight forward.

Maybe not so straightforward 😅

The rails 7 upgrade caused some unreproducible errors in production and I have created the following story to address the problems #378. The main problem is that samples extraction's test suite is not comprehensive enough to rely on. The relase was yanked so develop and master are back in a 'stable' state but the rails 7 upgrade needs to be re-attempted at some point.
