GH-535: [Dev] Use compose.yaml not docker-compose.yml

Fixes GH-535.

Because Docker Compose recommends `compose.yaml`:

https://docs.docker.com/compose/intro/compose-application-model/#the-compose-file

> The default path for a Compose file is compose.yaml (preferred) or
> compose.yml that is placed in the working directory. Compose also
> supports docker-compose.yaml and docker-compose.yml for backwards
> compatibility of earlier versions. If both files exist, Compose
> prefers the canonical compose.yaml.
