[docs] [issue29414] Change 'the for statement is such an iterator' in Tutorial

[Jim Fasarakis-Hilliard]

New submission from Jim Fasarakis-Hilliard:

The current line is confusing hinting that the for statement is actually an object, it also makes a reference to iterators which the tutorial doesn't disambiguate until the chapter on Classes.

I've added a small patch that, in my opinion, makes it clearer by using the terminology of the previous sentence.
