fix: correct sleep logic in kick_users loop

- Fixed a bug where a string literal "sleep" was passed to the delay function.
- Switched from blocking time.sleep() to non-blocking await asyncio.sleep() to ensure the bot remains responsive during large purge operations.
- The delay now correctly pulls the numerical value from self.config["sleep"].
