gh-126629 Allow the use of strings as loading or saving paths for JSON

Allow the use of strings as loading or saving paths for JSON.

It maintains the original API, but allows strings to be passed in when passing in file descriptors.This makes it easy to load or save JSON files.

Just like this:

import json

data = {
    "a":"b"
}
json.dump(data, "a.json")  # before: json.dump(data, open("a.json","w"))

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

This would need to be discussed on Discourse, just like #117946, https://discuss.python.org/t/file-path-support-for-pickle-dump-and-pickle-load/51488

I do have support for this in my own json library using read() and write(), but I'm not convinced it should be handled in load() and dump() because one argument becomes useless in this case.

I have read some discussions about this issue.I think this is a meaningless pull request, so I will close it
