#31157: JSONField are not properly displayed in admin when they are readonly.

-----------------------------------------+----------------------------
JSONField values are displayed as dict when readonly in the admin.
For example, `{"foo": "bar"}` would be displayed as `{'foo': 'bar'}`,
which is not valid JSON.
I believe the fix would be to add a special case in
`django.contrib.admin.utils.display_for_field` to call the `prepare_value`
of the `JSONField` (not calling `json.dumps` directly to take care of the
`InvalidJSONInput` case).
