Enhancement: display "Booking" as a set of attributes and not an object

Description

At the moment, when printing a "Booking" object, we get back a result of an object type. Even though that doesn't necessarily affect the way the application is running at the moment, it could cause problems in the future when debugging.
To identify the issue, follow the steps below.

In the CLI run:

1. python3
2. from lib.booking import Booking
3. booking = Booking(135, "2024-06-05 21:21", 1, 2, 3)
4. booking
   You will get a result similar to this:
   <lib.booking.Booking object at 0x1047a61e0>

To fix this I suggest adding a repl method in the booking.py:

_def __repr__(self):
    return f"Booking({self.id}, {self.dt}, {self.gid_id}, {self.user_id}, {self.ticket_count})"_

If afer adding the repl method we repeat the steps in the REPL, we should now be getting the result below:

Booking(135, "2024-06-05 21:21", 1, 2, 3)

Good observation - not sure we can justify it being high priority (the booking objects are only designed to be accessed/displayed via the front-end) but I can't see it causing any harm to make the suggested change, we'll have a think about doing this in a later sprint
