Fix: Correct example for UniqueTogetherValidator in serializer documentation

The example provided for using UniqueTogetherValidator in the serializer documentation currently uses an IntegerField for the room_number field. This is incorrect, as UniqueTogetherValidator is designed to work with relational fields, not integer fields.

This pull request replaces the IntegerField with a ChoiceField for the room_number field, which is a more appropriate field type for this scenario. This change ensures that the example accurately demonstrates how to use UniqueTogetherValidator with related fields.

Changes Made:

• In the example code snippet, the room_number field has been changed from:

  room_number = serializers.IntegerField(choices=[101, 102, 103, 201])

  to:

  room_number = serializers.ChoiceField(choices=[101, 102, 103, 201])

This minor correction will help users understand how to properly implement UniqueTogetherValidator in their serializers.
