Add support for sorting by json path

It would be nice to have the ability to sort the query results by a path of a JSON columns For example, for a table like

CREATE TABLE products (
  id serial NOT NULL PRIMARY KEY,
  translated_name jsonb NULL
);

I would like to have the ability to do something like

query productsSortedByName {
    products(order_by: {translated_name: {path: "en", how: asc_nulls_last}}) {
       id
       name: translated_name (path: "en")
   }
}

At the very least, we should be able to sort by a named path

so for a data jsonb column like this data: { "amount": 10 } and a query like this sometable { timestamp data amount: data(path: "amount") } You could sort by this "orderBy": [{"amount": "asc"}]
