Nightly Debian Tor packages on deb.torproject.org is broken since late 2023

Feel free to close this if we have another ticket elsewhere.

This was brought up in the relay operator community meetup today.

Our Nightly builds for debian is currently broken, and people would sometimes like to test Tor main instead of the release channels.

I think @micah had some conversations with folks on this topic, but I don't remember where we are with it.
