Link to `pprint` from `json.dump[s]()` about cpython

It has nothing to do with JSON, I do not think that such link is relevant. It can even cause confusion, because the subset of Python syntax is compatible with JSON, this can look like suggestion to use pprint to produce JSON.

I think the number of people who use json to print out python objects, who would also read the json documentation and find a pprint reference to do something sort of (but not really) related is very, very small. I don't think this should be added.

JSON is not only used for storing data, it's also used for displaying information in human readable form, we even have an example of that in the documentation. I have messed around with custom JSON encoders while there's a module that supports them out of the box. This is precisely why it would have been useful to link to that module. And like shown above, using it to print a list of lists doesn't work well.

I didn't search for a different way to do it, because I already knew json, which works in most cases. But in others I had to use a for loop.

Let me know if you change your mind.
