Cloud MTA Build Tool Docker Image

[rafaelferrari]

Hi team, the docker image currently listed under Cloud MTA Build Tool in the README is currently marked as deprecated on Docker Hub, and its last update was 3 years ago: https://hub.docker.com/r/devxci/mbtci

Do you have another recommended official docker image with this tool? Or is the official guideline fetching a node image and installing mbt as a global dependency? Having a docker image that does just that would already be helpful I think, but maybe this one should be removed from the list if it is no longer supported.
