Update to 1.123
    
    - New upstream release 1.123
      - Now requires PPI-1.220 which has numerous bug fixes; this may eliminate
        the need for some "## no critic" markers you inserted to work around those
        bugs - the "ProhibitUselessNoCritic" policy should help you find them
      - Fixed a typo in the Variables::ProhibitPerl4PackageNames message
