Hi! Scaling is a great feature, thanks for adding it! However, I believe there might be a mistake in [line 163](https://github.com/Farama-Foundation/Minigrid/commit/8710e91d2325b5e5e1ce75dae5567fd816298ca7#diff-ab54a375e8276130784ec5e60fcf593a7331799ca458219cb011c2b0dfcc9c8fR163). Currently, it is written as: `self.scale = 1` I think it should be: `self.scale = scale` Could you confirm if this is indeed an issue? Thanks!
