Refactor recipes to add Trixie based images #52
Description
Debian Trixie is probably right around the corner, so having images for that and refactoring the recipes and repo situation to deal with that would be great. There should be no awkward surprises for users upgrading their plebian devices from bookworm to Trixie.
We might also be able to do graphical desktop images as an added option with Trixie, since the newer sddm will no longer hang on shutdown.
