Update docker-compose.yml to version 2.2 The current docker-compose.yml is still in version 1, which is deprecated: https://docs.docker.com/compose/compose-file/compose-versioning/ So if you try to run `docker-compose up` with a recent version of docker-compose, the following error occurs: (root) Additional property mysql is not allowed Version 2.2 was chosen because it's not deprecated, but it also has been released some time ago: Compose version 2.2 requires docker engine version 1.13.0, which was released on 2017-01-18. So, with this version, hopefully no users will have any issues either with deprecation warnings or with a version that is not yet supported by their docker-engine. 2021-12-05 15:24:03 +00:00			`version: "2.2"`
