[AUDIT][SPARK-48148][CORE] JSON objects should not be modified when read as STRING

[abellina]

apache/spark@b47d7853d92 fixes an issue where json objects read as a string were not being rendered in the string as they were in the json, instead there is processing happening and things like float columns would round differently (according to the example given). This can later be used as input to from_json and the issue is from_json has different input to work with.

As we do work with json this would be an issue to keep an eye out for. @revans2 @winningsix fyi.

That does make this much more fun :)
