QLocale: improve documentation snippet
QString::toDouble() now always uses C locale, so the previous code
snippet does not make much sense, as the results do not depend on the
selected default locale.
The updated snippet uses the default locale, which allows to show the
difference between locales.
Pick-to: 6.2
