Enhance RsTab Component with New Props and Improved Slot Handling

- Added support for tabs to be passed as props, allowing for a more flexible tab configuration.
- Implemented a watch on modelValue to synchronize selected tab changes.
- Enhanced slot handling to accommodate both named slots and default slots for better usability.
- Refactored tab selection logic to utilize helper functions for improved readability and maintainability.
