Update the Debian stable release to trixie
# Description
Update Debian stable release to `trixie`.
# Tasks
* [x] Update the `latest` tag on Debian images pointing to `trixie`, once it's released (at [onion-services/containers.yml](onion-services/containers.yml).
* [x] Create a ticket for the next stable release (setting due dates so we can track this properly), and so on.
* [~] Or maybe find a way to derive this information from `debian-distro-info --stable` from the [distro-info][] package, so this gets automated.

# Time estimation
* Complexity: negligible (0.1 day)
* Uncertainty: low (x1.1)
