Updates for CVE-2023-51074 and CVE-2023-5072

Updates the org.json.json and com.jayway.jsonpath.json-path libraries which fix CVE-2023-51074 and CVE-2023-5072.

Had to make code changes because the json-path library introduced a bug in the updated version which fails a few unit tests in our repo.
See this PR to track the issue json-path/JsonPath#871
