refactor: update getRoomRecordUrl method in MinioService for improved promise handling

- Changed the implementation of the `getRoomRecordUrl` method to use `await` with the Promise constructor for better readability and consistency.
- This adjustment enhances the asynchronous handling of the method, ensuring a more straightforward promise resolution process.
