Cubes skeleton is not up-to-date
- The generated Dockerfile is not working with CW4, we should use
logilab/cubicweb-base:cw4-postgres16-bullseye
as base image. - The generated gitlab-ci is not using latest template (which are on branch/v2)
logilab/cubicweb-base:cw4-postgres16-bullseye
as base image.
