Silence some SyntaxWarnings from Python 3.12+:

      ('^(r[0-9]+) \| ([^|]+) \| ([^|]+) \| ([0-9]+)[^0-9]')

    contribulyze.py:579: SyntaxWarning: invalid escape sequence '\s'
      + ' by:\s+|\s+)([^\s(].*)')
    contribulyze.py:706: SyntaxWarning: invalid escape sequence '\S'
      matcher = re.compile('(\S+)\s+([^\(\)]+)\s+(\([^()]+\)){0,1}')

* tools/dev/contribulyze.py: Use r-strings to appease the Python regex
    parser.
