Issue HER-53: Update Booking Model to Allow for Modifications

https://raquelanaroman.atlassian.net/browse/HER-53

Description

As a teacher user, I want to be able to modify the booking times within the availability window.

Acceptance Criteria

The Booking model needs to be associated with the Availability model to get the window of availability.

Create a migration to add Availability reference to Booking.

class AddAvailabilityToBookings < ActiveRecord::Migration[7.2]
  def change
    add_reference :bookings, :availability, foreign_key: true
  end
end

Update the models:

Booking Model:

class Booking < ApplicationRecord
  belongs_to :availability
  # other associations and validations
end

Availability Model:

class Availability < ApplicationRecord
  has_many :bookings
  # other associations and validations
end

Update the controller logic:

def update
  booking = Booking.find(params[:id])
  availability = booking.availability

Everything else remains the same as HER-58
