[enhancement] Add Polish translate

[sykmer]

Hello,
Can you add polish translate ?
Thank you

[Ghostkeeper]

Since I don't speak Polish, I couldn't make those translations myself. If there is a volunteer who is willing to help with the translations, those additions would be welcomed, though, just like the current translations.

Instructions for creating translations are here: https://github.com/Ghostkeeper/SettingsGuide/blob/master/contributing.md#translating
