[docs] QString: fix link and formatting in the qPrintable() discussion

The old code used a `<QString>` to indicate an object of QString
type. I have not seen this pattern used elsewhere, so rewrite the
expression to say "call X on the QString" instead of "call
<QString>.X".

Also, the constData() link in the expression ('X' in the previous
paragraph) was unqualified, so resolved to QString::constData(), but
the result of toLocal8Bit() is a QByteArray, and it's thence the link
should point to. Redirect it manually whereever we fell into that
trap.

Amends the start of the public history.
