Remove foreach snippets from the documentation

We don't recommend foreach anymore, and have in fact
adapted two snippets already to use for(), but missed
the documentation text.

In any case, it feels a bit weird to give an example
how to iterate over QStringList in each of these methods,
so we might as well just remove this part.

Pick-to: 6.6 6.7
