feat(settings): add Slovak language support for spell check (#11664)

* refactor(settings): move spell check languages to constants and add type

Add Slovak language option and define SpellCheckOption type for better type safety

* fix(settings): disable spell check selector on Mac platforms

The spell check selector should not be shown on Mac platforms as it's not supported. This change adds a platform check to hide the selector when running on macOS.
