[breakthru] I've fixed the issue, we work now

So... yeah... Docker does what you tell it too... including placing
'mod_data' directory/docker volume into a place that it shouldn't be,
thus not found by luanti, and thus failure to mkdir (as this wouldn't be
saved, except ugly in the container)

Now that we place it where it needs to be, and updated to a newer Debian
(Introduce Debian 13-14? Trixie)
