Docs indicate that IntegerField takes a choices parameter

[rmcloughlin]

I'm reading the docs, and in this section the second example contains this line:
room_number = serializers.IntegerField(choices=[101, 102, 103, 201])
But if I try to run that code I am shown:
TypeError: Field.__init__() got an unexpected keyword argument 'choices'

[browniebroke]

This is already fixed in the docs source (fixed in #9563):

django-rest-framework/docs/api-guide/serializers.md

Line 236 in 9016efe

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

So I assume it's a deployment issue, we usually update them when we make a release.
