docs: // CmdVersion returns a "version" subcommand that prints to stdout the given
  // version as well as CIPD package name and the package instance ID if the
  // executable was installed via CIPD.
  //
  // If the executable didn't come from CIPD, the package information is silently
  // omitted.
  //
  // 'version' will be printed exact as given. The recommended format is
  // "<appname> vMAJOR.MINOR.PATCH".
