tracktrain: update

This is the initial version for this year's run of absurd train
operations. I won't dare to call it a release for at least another month
or so, so no version number.

Changes done in our nixfiles:
 - tracktrain now needs ntfy-sh so people (read: I) can get push
   notifications if things break or at least look a little weird
 - I removed the grafana instance; seems like somewhere in the last year
   they changed how to host it under a sub-path (ours was at /metrics),
   so it broke, and I'm not feeling any particular urge to fix it
 - last year's database contents have been yoten
 - also manually updated the gtfs (though I intend to implement logic
   for fetching it in tracktrain, I first need to drag Ilztalbahn into
   actually publishing up-to-date versions again first)
