Fix: Correct example for UniqueTogetherValidator in serializer documentation

The example provided for usingUniqueTogetherValidator in the serializer documentation currently uses anIntegerField for theroom_number field. This is incorrect, asUniqueTogetherValidator is designed to work with relational fields, not integer fields.

This pull request replaces theIntegerField with aChoiceField for theroom_number field, which is a more appropriate field type for this scenario. This change ensures that the example accurately demonstrates how to useUniqueTogetherValidator with related fields.

Changes Made:

• In the example code snippet, theroom_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 implementUniqueTogetherValidator in their serializers.
