Rename docker-compose.yml to compose.yaml

[bobbyiliev]

As per the new Docker naming convention described in the docs here, renaming the docker-compose.yml to compose.yaml.

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.

How long has support for compose.yml been out in the wild? I wonder if this could break things for people using older tooling that doesn't yet support the new convention.

Yea, good point! Managed to find when the support for the compose.yml and compose.yaml was actually introduced and it seems like it's been there for quite a while already: https://docs.docker.com/compose/release-notes/#1286

My guess is that they will keep the docker-compose.yaml fallback for quite a while!
