Improve data in Purchase Events

Using the 'purchase' event in the 'Custom Booking Flow' on https://accessgroup.my.site.com/Support/s/article/Access-Collins-Use-Google-Analytics-4 as an example.

I would expect the value and item price to accurately reflect the value of the purchase and items in the transaction and not always report 0 as can be seen in the example.

Also, the quantity of the Booking item to show as 1 rather than the number of different items in the purchase. In the example the quantity is 2, when normally bookings are made individually.

Lastly, the items array to contain an object for each item in the purchase with accurate prices and quantities. So there would be one object for the booking and one object for each additional unique item.
