fix: fix missing spacing in review decision response (#2457)

This PR fixes a display issue inside the user approval widget:

<img width="396" height="62" alt="Screenshot 2025-08-19 at 16 42 13"
src="https://github.com/user-attachments/assets/a67da78b-7e9c-4f65-8b56-06644713ce8f"
/>

The other review decision responses are already properly formatted.
Thanks!
