Doc: Improve documentation for QLocale::FormatType

LongFormat and ShortFormat are not limited to day and month names.
Different locales might also use numbers for months instead of strings,
so the example is a bit misleading.

Instead of extending the enum description even more there's now
examples in the dateFormat(), timeFormat(), dateTimeFormat()
functions.
