[FEA] JSON reader should parse quoted floating point values as null

[andygrove]

Is your feature request related to a problem? Please describe.
Given the following JSON file, Spark will produce the values 1.0 and null, but on GPU we would produce 1.0 for both rows (once #4637 is merged).

{ "number": 1.0 }
{ "number": "1.0" }

Describe the solution you'd like
We should have consistent behavior with Spark. We need to remove the XFAIL from the test in json_test.py that references this issue.

Describe alternatives you've considered
None

Additional context
None

I don't see a JSON file attached or anywhere here.

Also this is going to be impossible to do without help from CUDF. If we are really concerned about this we are either going to have to have CUDF parse all of the values the way Spark wants them to be parsed, which I don't think will ever happen, or we need a way to get a boolean back that this was quoted or not in the original data. If we want the later we are going to need to request it from CUDF as a part of their JSON rewrite.

I filed a feature request against cuDF - rapidsai/cudf#10283

I also update the issue description to include the sample JSON that I forgot to include when originally filing this issue.

This was fixed as a part of #10542, but I didn't realize it because of all of the other tests that xpass as a part of JSON. So I just removed the xfail as a part of #10575
