Found in version set to 9.6

The 9.6 version of parse-json() was designed only to handle a map or array as the top-level JSON construct. I'm patching the code so it produces sensible diagnostics if this isn't the case. The 9.7 version handles singleton items such as strings or numbers at the top level.
