[Bug Report] shallow copy of info and observation after termination

[VictorTao1998]

Describe the bug

when using async_vector_env, the info after termination of one episode is wrong, it returns the info from reset() instead of step()

Code example

in gymnasium/vector/async_vector_env.py 642:646
if terminated or truncated:
                    old_observation, old_info = observation, info
                    observation, info = env.reset()
                    info["final_observation"] = old_observation
                    info["final_info"] = old_info

I think there should be a deepcopy for the old_observation and old_info here.

System info

gymnasium==0.29.1

Thanks for the issue but your message and title seem to be about different things.

1. For when reset occurs (autoreset), for gym < 1, this is intentional and we are changing this in v1.0
2. For no deepcopy of obs, info, could you provide an example where this is an issue?
