Docs: Fix day/year format in QDateTime

QDateTime takes dd and yyyy.  It is confusing when the example format
strings don't work because they use DD YYYY, and it is a silent error
with the characters not getting substituted and can be easy to miss.

Improved Qt::ISODate, TZD isn't a format character so skip writing out
a bad format example.
