New Service: Joplin notes server

[vvstubbs]

I use Joplin all the time ran it through my internet domain for quite a while but I'm migrating everything to run private through tailscale so it would be great to have Joplin - https://github.com/laurent22/joplin/blob/dev/docker-compose.server.yml

Thanks for the suggestion, when I have time I will try to get it working!
