Remove redundant qualifier from RulesBean initialization (#3738)

- Removed the redundant qualifier `V2rayConfig.RoutingBean.RulesBean` in favor of directly using `RulesBean`.
- This simplifies the code and improves readability by removing unnecessary fully qualified names.
- The change ensures cleaner and more maintainable code without altering functionality.
