Update to 0.009
    
    - New upstream release 0.009
      - Fixed error in synopsis (we do not export anything by default)
      - A caveat added to the documentation regarding embedding warning checks
        inside another sub
      - ':no_end_test' now also covers side effects of done_testing, as well as
        END blocks, making it possible to use the warning(s) subs without having an
        end warning test while using done_testing (necessary when combining with
        the 'if' pragma)
      - END tests will not be added by a subequent use of Test::Warnings if a
        previous one passed ':no_end_test'
    - Update dependencies
