Update booking
Change dates, hours, people, project or the tentative flag of a booking.
PATCH https://cotlet.dev/api/v1/resource-guru/bookings/{booking_id}
write Confirm
Returns the booking after the change. On a multi-resource booking the change applies to every resource on it. Confirming a tentative booking shows it on the booked people's Dashboard, and with the Approval Workflow on it can come back pending. By default you confirm each call; you can switch that off for this tool.
