Clarify Booking.com Review Detection Limitation

Problem: Hosts are currently unaware that the "Do not send if a guest has already published a review" setting only applies to Airbnb and does not work for Booking.com. This leads to guests receiving review requests even after they have already left a review.

Current Workaround: Hosts must manually monitor the activity log and cancel scheduled review requests for Booking.com guests who have already reviewed.

Impact: This creates additional manual work for hosts and can lead to a poor guest experience when guests receive redundant requests.

Proposed Solution: Better inform hosts within the messaging rule settings that this specific automation is currently limited to Airbnb.

Unlock: Hosts will have clearer expectations of the system's capabilities and can manage their Booking.com review requests more effectively.
