Minimize image size - v3.1.1 image is 1.09 GB big

% docker image ls | grep source
ghcr.io/sourcebot-dev/sourcebot v3.1.1 7970895577df 24 hours ago 1.09GB

Does this need to be this big?

If self-hosted folks are using external PostgreSQL + Redis, perhaps those don't need to be packaged into the image (could provide a separate "minimal" image maybe?)

Heya - yea the idea of offering separated images for each service was brought up in #261 - the tl;dr is it's something we are thinking about, but it will probably be part of a wider "horizontal scaling support" effort for Sourcebot.

I inspected the image, and this layer that installs postgres, redis and other dependencies accounts for only 176MB. So breaking out those dependencies alone wouldn't really impact the image size v much
