Remove Docker Compose version from YML files and set networks to external

The Docker Compose version definition was removed from traefikContainer, portainerContainer, and opensshContainer functions. The "external" attribute was also added to "traefik" and "openssh" networks. These changes aim to improve the versatility and compatibility of network settings and remove unnecessary version constraints.
