Replace AutoResetWrapper by a HideTerminationWrapper

`gymnasium` as an [AutoResetWrapper](https://gymnasium.farama.org/api/wrappers/misc_wrappers/#gymnasium.wrappers.AutoResetWrapper) that behaves close to ours but it does not hide the termination conditions. We should use the upstream AutoResetWrapper and just provide one that does nothing but hide the terminated/truncated signals and use that in combination with the gymnasium.AutoResetWrapper.
