docs(tauri): clarify script serialization in execute function

- Added a comment in the `execute` function to explain that TypeScript sends scripts as-is, necessitating serialization for proper handling.
- This change enhances understanding of the script processing logic, ensuring clarity on the serialization step for arguments passed to the function.
