https://datahubproject.io/docs/quickstart/ is still saying to install docker-compose v1 (ie docker-compose). however, in https://github.com/datahub-project/datahub/commit/20138a32e56eb7dae3db61f967364b591ddd8be0 the quickstart has shifted to using v2. (docker compose) The documentation needs to be updated.

thanks, we will update our docs

an announcement would probably also be suggested for existing users as well.
