[docs] [issue21092] json serializer implicitly stringifies non-string keys

Berker Peksag added the comment:

This implicit stringification of non-string dictionary keys does not currently appear to be documented.

I think this is part of the JSON spec. See http://json.org/object.gif for example. Also, this is already documented in the json.dumps() documentation:

Keys in key/value pairs of JSON are always of the type str. When a dictionary is converted into JSON, all the keys of the dictionary are coerced to strings.
