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.
