WooCommerce Bookings: Automatically Block Other Resources When One is Booked

block_resources.php

/* 

This snippet ensures that when a booking is paid for a booking product with multiple resources, 
all other linked resources are automatically blocked for the same time slot. It dynamically adds 
an availability rule within the booking product blocking the slot, preventing other resources bookings for that slot.
