Template using syntax docker-compose v2 "depends_on", but docker-compose version: '3.7'

Created by: yevhen-kalyna

Issue:

$ docker-compose -f deploy/docker-compose.yml --project-directory . build
ERROR: The Compose file './deploy/docker-compose.yml' is invalid because:
services.api.depends_on contains an invalid type, it should be an array
services.migrator.depends_on contains an invalid type, it should be an array

In docker-compose file:

    depends_on:
      db:
        condition: service_healthy
      redis:
        condition: service_healthy

Should be:

    depends_on:
      - db
      - redis
