Merged PR 5353: Switch int_core__booking_summary to int_booking_summary

# Description

This PR does the following:
* Moves `core/int_core__booking_summary` to `cross/int_core__booking_summary`
* Renames the model `cross/int_core__booking_summary` to `cross/int_booking_summary`
* Same for schema entry. In the new schema, I just added in the description how to retrieve exclusively New Dash Bookings for usability purposes.

Then, it adapts any dependency on `int_core__booking_summary` to `int_booking_summary`

No additional changes - inclusion of Resolution Incidents data will come later in a different PR.

# Checklist
