I'd like to propose a minor changes that can bring more stability in launching the umami server with docker-compose by adding a certain healthcheck for db container and a certain condition for depends_on directive for umami-app container
It might be a good idea to add a restart policy to the default `docker-compose.yml` file.
Either: `restart: always` or `restart: unless-stopped`
Useful in case Umami crashes for some reason (see #721)
This is also useful in case the server restarts, so Umami starts up again after rebooting.
