`docker-compose` should be replaced with `docker compose`

[shermanlo77]

docker-compose should be replaced with docker compose following the commits in 123andy/redcap-docker-compose@1a0e412. This is so that Docker Compose v2 can be used instead of v1. Support for Docker Compose v1 is planned to be dropped.

At the moment, install REDCap produces the following error for me

( ! ) Warning: mysqli::__construct(): php_network_getaddresses: getaddrinfo for db failed: Tem
porary failure in name resolution in /var/www/html/REDCapInstaller.php on line 347
