fix(workflow): change old docker-compose call to new ``docker com…

…pose`` (#1383)

The "Backend | docker-compose database" flow did not work anymore with the following error:

Run docker-compose -f docker-compose.yml up --detach --no-deps database
The Compose file './docker-compose.yml' is invalid because:
'include' does not match any of the regexes: '^x-'

You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
Error: Process completed with exit code 1.
