Subject: [PATCH] Web container waits for DB container to be ready

Fixes the setup issue almost all Raspberry Pi users have and probably some others with slow or low spec systems.
The web_recipes container waits for db_recipes to be healthy.
db_recipes is healthy, as soon as postgres is completely ready.

Note: ps_isready doesn't work here for some reason.

Tested multiple times with a Raspberry Pi 4.
