This installs the golang based compose (v2) tool. Also make it the
python based tool optional, but installed by default.
The docker compose v2 tool comes from either:
- Disrto : Moby Engine : docker-compose-v2 : Focal -> Oracular
- Upstream : Docker Inc : docker-compose-plugin : Trusty -> Noble
With manual checking I can't see any distro older than focal that makes
use of the install-docker role, and all in-tree users pull from
upstream, so I think adding the golang compose tool without checking
the release is safe.
