[Bug Report] step and info structures expected to be identical (when `record_infos=True`)

[Kallinteris-Andreas]

Hey, I am trying to make dataset of Ant-v5 and i am getting this error:

$ py create_dataset.py  # expert-v0
Traceback (most recent call last):
  File "/home/master-andreas/gym/rl/project/create_dataset.py", line 56, in <module>
    obs, rew, terminated, truncated, info = collector_env.step(action)
                                            ^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise ValueError(
ValueError: Info structure inconsistent with info structure returned by original reset.

for reference: self._reference_info is set using info from reset https://github.com/Farama-Foundation/Minari/blob/9803a700bdba1e228e335de5422511edbfb4c74e/minari/data_collector/data_collector.py#L261

which is then compared to the info from reset https://github.com/Farama-Foundation/Minari/blob/9803a700bdba1e228e335de5422511edbfb4c74e/minari/data_collector/data_collector.py#L147

Also in general, it is not in Env's specification that info s need to have the same structure each time https://gymnasium.farama.org/main/api/env/#gymnasium.Env.step
