Thanks that's amazing. Can you add a quick test in test_libs.py for this feature?

@matteobettini I guess this slipped through as we don't do a check_env_specs when return_state=True?

This is super strange, state should have already been present in resets and step as also benchmarl is using it, let me have a look tonight. I might have missed something major!

The chaced zero specs meant that the states are there but they were all zeros that is why me or the checks never got this
