Subject: [PATCH] fix: docker compose link (#2914)

The current docker-compose.yml fails to start today with an error:

service "atuin" depends on undefined service "postgresql": invalid
compose project

This patch modernizes the yml and fixes the link. Tested on docker
compose v2.39.4.

Docs patch is https://github.com/atuinsh/docs/pull/104 .  /cc @ellie
