Update cli_getCopyrightInfo.sh:
    
        - Stop using `--copyright-holder' option as default action when no
          argument is passed to cli_getCopyrightInfo function. Instead,
          add `--copyright' option and start using it. The `--copyright'
          option combines both the `--copyright-holder' and the
          `--copyright-year' options to build the full copyright notice as
          `Copyright © YEAR HOLDER'.
