class_docstr: Converts infos of vectorized environments from dict to List[dict].
  
  This wrapper converts the info format of a
  vector environment from a dictionary to a list of dictionaries.
  This wrapper is intended to be used around vectorized
  environments. If using other wrappers that perform
  operation on info like `RecordEpisodeStatistics` this
  need to be the outermost wrapper.
  
  i.e. VectorListInfo(RecordEpisodeStatistics(envs))
  
  Example::
  
  >>> # actual
  >>> {
  ...      "k": np.array[0., 0., 0.5, 0.3],
  ...      "_k": np.array[False, False, True, True]
  ...  }
  >>> # classic
  >>> [{}, {}, {k: 0.5}, {k: 0.3}]
docstr: Steps through the environment, convert dict info to list.
code: def step(self, action):
      """Steps through the environment, convert dict info to list."""
      observation, reward, terminated, truncated, infos = self.env.step(
          action
      )
      list_info = self._convert_info_to_list(infos)
  
      return observation, reward, terminated, truncated, list_info
