    gitlab-ci: expire the Windows installer artifact after a week.
    
    Currently we run the job on a weekly schedule. If we keep a retention
    period of 2 days, it means that people will not have access to a nightly
    Windows installer 5 days out of 7, which is not useful.
    
    Gitlab has a retention policy not to delete artifacts for last jobs, but
    it apparently actually bases this check on being the last pipeline, not
    being actually the last job of a given name. Since we have pipelines
    running all the time, this retention policy just won't apply to our
    installer job which will get deleted.
