self.progression not reset in reset babyai

[jens321]

It seems the self.progression variable is not reset in the reset function here https://github.com/balrog-ai/BALROG/blob/main/balrog/environments/babyai_text/clean_lang_wrapper.py#L45-L54. It makes it so that once one episode has been successful all future ones will also get progression = 1.0. Is this intended? If not I'm happy to make a PR to fix it.

Thanks for pointing this out! Luckily this is not a problem affecting BALROG, as we are never actually resetting environments but always creating completely new instances from the evaluator manager, which makes sense due to the highly parallel nature in which BALROG is supposed to be run.

However this will be a problem for people using the BALROG make_env function outside BALROG, feel free to open a PR to fix this!

Fixed in #31, closing the issue!
