SQL/JSON: Update example in JSON_QUERY() documentation

Commit e6c45d85dc fixed the behavior of JSON_QUERY() when WITH
CONDITIONAL WRAPPER is used, but the documentation example wasn't
updated to reflect this change. This commit updates the example to
show the correct result.

Per off-list report from Andreas Ulbrich.
