Describe the enhancement requested
The Dataset JSON test currently uses RapidJSON for generating JSON test data in cpp/src/arrow/dataset/file_json_test.cc.
Replace the RapidJSON-based writer with Arrow's existing json::JsonWriter, removing the direct RapidJSON dependency while preserving the existing test behavior and JSON output.
