docker: migrate to Docker compose v2

Docker compose v1 has been deprecated since July 2023 [1]. Now the
GitHub actions Ubuntu runner images removed it, too [2]. So move to v2.

labgrid is obviously not affected by any changes between v1 and v2 other
than the compose call docker-compose -> docker compose.
