[docs] [issue34077] doc Be explicit about mock_open created mocks not supporting __iter__

[Andrés Delfino]

New submission from Andrés Delfino <adelfino at gmail.com>:

I've been bitten by this one, and while the docs are clear in what the created mock objects support, I think something explicit about __iter__ will help.
