Use same Docker image as the GitLab project for Gitpod
I notice when we use the default Gitpod images, we get the message Required ruby-2.7.4 is not installed.
.
Because the gitlab-docs
project likes to use the exact same dependencies as gitlab
project, provided for by GDK, we should probably use the same image setting as gitlab
