typo correction PR :tropical_drink:

[Lukas113]

I was conflicted what to do about the polarization. I wanted to change everything to polarization, but some API's are British English and not American. However, usually we (and most other libraries) use American English. I kept it British atm. Maybe wrong decision?

I also didn't change everything, because I was afraid of breaking some code. This PR was just meant to be an easy fix-typo thing.

Probably fine to leave it for now.
