Model docs Field.choices inconsistency between reference and topic guide

[Zowie Beha]

​https://docs.djangoproject.com/en/5.0/ref/models/fields/#django.db.models.Field.choices

On this reference page, Field.choices is described as:
"A mapping or iterable in the format described below to use as choices for this field."

​https://docs.djangoproject.com/en/5.0/topics/db/models/#field-options

Here on the topic guide however, the description is:
"A sequence of 2-tuples to use as choices for this field."

A mapping is used as an example in the topic guide, however it might be better to mention explicitly/upfront all valid choices values (such as callables for example).
