Rename docker-compose-dev.yml file

[maggie44]

Standard docker naming conventions suggest the file should be docker-compose.dev.yml. At the moment however, Balena CLI uses that file naming convention for a different use case which would conflict if the file was renamed.

Have requested the conflicting Balena feature be changed to follow standard docker conventions:
balena-io/balena-cli#2241 (comment)
balena-io/balena-cli#1142 (comment)

Balena also doesn't support specifying a specific docker-compose file to use for building. Ideally the development environment would be docker-compose.yml and the production docker-compose.prod.yml. Feature request has already been made to specify a docker-compose file for production building: balena-io/balena-cli#1142
