docs: Install the user provided entry point to be executed as follow:
          - add the path to sys path
          - if the user entry point is a command, gives exec permissions to the script
  
      Args:
          name (str): name of the script or module.
          dst (str): path to directory with the script or module.
          capture_error (bool): Default false. If True, the running process captures the
              stderr, and appends it to the returned Exception message in case of errors.
