Add GetStructuredData method to JSON handlers

Introduce a new method `GetStructuredData` in the `ExtractOperationHandler`, `MapOperationHandler`, and `TransformOperationHandler` classes. This method converts JSON tokens into a structured format as a list of dictionaries, enhancing the `PluginContext` with a new `StructuredData` property for better data representation and processing.
