fix: correct CheckTrue usage in docker-compose test

Fix lint error by replacing t.CheckTrue with proper error checking.
CheckTrue only accepts one argument (bool), not a message.

Changed from:
  t.CheckTrue(len(containers) > 0, "message")
To:
  if len(containers) == 0 {
    t.T.Fatal("message")
  }

This matches the pattern used in other integration tests.
