GEODE-10459: upgrade testcontainers

The acceptance tests appear to fail because `docker-compose` does not
exist. Likely the GHA machines have moved to the new `docker compose`
convention. This attempts upgrading testcontainers, as testcontainers is
what's starting docker compose, and newer versions indeed do it through
the `docker` executable.
