fix(sidebar,flyout): remove unused ios checks

This PR removes leftover and unused/ineffective code to check for ios browsers. The whole codebase does not have any class reference to .ios anymore.
This was already removed in SUI 2.2.11 almost 6 years ago via Semantic-Org/Semantic-UI@da0aff0 , but it was forgotten to clean up the code entirely.

As set.ios as well as any .ios selector was removed, any additional codechecks don't have any impact, so it's safe to delete without tagging as breaking change
