ci(ci.sh): fix Docker Compose presence check - migrate to sub-command

1. The old way to use docker compose was through the standalone binary
`docker-compose`
2. This was working for a while but now the auto-upgrades that we cannot
seem to avoid have caught up with us and broke ci.sh in the GitHub action
runners because the standalone binary is no longer available at all and
therefore the migration must happen.
3. Point 2 is just a theory but one that is considered to be very likely
correct.
4. It is to be seen if we'll have any other downstream issues such as the
tests failing in other ways due to this underlying docker change.
