🐛(compose) set lasuite network as external

The docker network lasuite is created in the makefile using the command
`docker network create lasuite-network`. When a network is created with
this command it can not be used by docker compose if this one is not set
as external. We must use `external: true` in the compose file to fix
this issue.`
