[Bug Report] Error after updating to MiniGrid 1.2.0

[ibagur]

Describe the bug
I have upgraded to MiniGrid 1.2 (after updating to gym 0.26), but for some reason I cannot get it run. I have forked and cloned the repository so to download the code, but haven't performed any changes to it yet.

Code example

I try to run just the manual control script over a simple environment:

./gym_minigrid/manual_control.py --env MiniGrid-Empty-5x5-v0

I get the following errors:

Traceback (most recent call last):
File "./gym_minigrid/manual_control.py", line 102, in
env = gym.make(
File "/Users/inigo/.local/share/virtualenvs/test-minigrid-ZLPD9hGZ/lib/python3.8/site-packages/gym/envs/registration.py", line 652, in make
raise e

cd gym-minigrid
pip3 install -e .

It seems something related to 'new_step_api' argument, but I cannot relate it to other issues that made reference to it
