Adjust incognia.Dockerfile to set a working yarn version

The "yarn set version berry" downloads the yarn version 4, but it
is not compatible with the node version currently used in this project.
Note that the yarn v3 is being used, because the yarn v2 is downloading
the workspace-tools using the wrong URL, so it would break the build.
