Update tcar_printUsage function.
    
    - Previously, the command in usage block was printed before the
      "--version" and help "--help". This infer the "--version" and
      "--help" options to be related to "<command>" instead of "tcar".
      This updates rearrange the usage block to relate both "--version"
      and "--help" options to "tcar" instead of "<command>"
    
    - Previously, the sentence describing the command used to get more
      information was not prepared for localization. This made impossible
      for translators to provide different language translation strings
      for it. This update prepares the sentence describing the command
      used to get more information in order for translators to provide
      different language translation strings for it.
