docs: update `docker-compose` commands to Docker Compose V2 syntax

The project prerequisites already require Docker Compose v2+, but command
examples still used the legacy `docker-compose` (hyphenated) form. Replace
all command invocations with `docker compose` (space-separated) while
keeping file name references (docker-compose.yml, etc.) unchanged.
