    gitlab-ci: split a bit more the CI build.
    
    Though now the whole build happens under 1 hour, some of the jobs are a
    bit too close to the timeout to my taste (some take 55 mins). So let's
    split languages into a fourth job.
    
    Also no need to build the landing pages several times. So let's create a
    specific job to assemble the result of all 4 split jobs and build the
    landing page into a separate final job.
    
    (cherry picked from commit bb9ffcaefbf85567938374c214184e907057e9f9)
