Proposed changes

The mandatory variable syntax is only available in docker-compose 1.19+ (docker/compose#5531). However, no new compose file version was created to reflect this change, nor is this documented.

Adding this information for clarity.

Related issues (optional)

Fixes docker/compose#5683.

@zypA13510 Thanks for the PR. The suggestion looks obsolete given the latest version is Compose V2 - https://docs.docker.com/compose/compose-v2/. Closing this PR for this reason.
