Migrate to Compose V2

From July 2023 Compose V1 stopped receiving updates. It’s also no
longer available in new releases of Docker Desktop.

Compose V2, which was first released in 2020, is included with all
currently supported versions of Docker Desktop. It offers an improved
CLI experience, improved build performance with BuildKit, and continued
new-feature development.
