    Fix build process of PDF docs on macOS and update .gitignore
    
    Note: the syntax of command/switch `sed -i` is slightly different
      on macOS vs. Linux and should not be used.
    
    Move .gitignore parts referring to /documentation/ to their own file
      'documentation/.gitignore' and add new generated file(s).
