How to sort with `NULLS LAST` clause?

[svanschooten]

As we have some data in nested JSONB columns, we use the additionalQuery to add select and ordering for these columns, we need to do this manually is because we need put null values last, which (afaik) is not possible with the JsonApiParams. However, this introduces certain complications, such as also needing to inject your own select clauses for the columns we want to sort on.

Is there a way we can define to sort the nulls last?

I would happily accept a PR that address this request
