Return a reference providing modifiable access to the `Json` object associated with the specified `key` in this `JsonObject`; if this `JsonObject` does not already contain a `Json` object associated with `key`, first insert a new default‐constructed `Json` object associated with `key`. The behavior is undefined unless `key` is valid UTF‐8 (see `bdlde::Utf8Util::isValid`).
