Doc: improve documentation for UNNEST(). Per a user question, spell out that UNNEST() returns array elements in storage order; also provide an example to clarify the behavior for multi-dimensional arrays.
While here, also clarify the SELECT reference page's description of WITH ORDINALITY. These details were already given in 7.2.1.4, but a reference page should not omit details. Back-patch to v13; there's not room in the table in older versions.
