docs: Sets the random seed of the environment to the given value (current time, if seed=None).
          Naturally deterministic Environments (e.g. ALE or some gym Envs) don't have to implement this method.
  
          Args:
              seed (int): The seed to use for initializing the pseudo-random number generator (default=epoch time in sec).
          Returns: The actual seed (int) used OR None if Environment did not override this method (no seeding supported).
