Fix iOS Picker Item Colors

Summary:
I want to resolve #11170 by passing the `color` prop from `PickerIOS.Item` to its implementation.

In `RCTPicker.m`, the label.textColor was already being set and used, but there was nothing referencing the past prop. I passed the prop to the implementation, checked if it exists, and if not, set the default color, like before.

I visually tested the **Colorful Pickers** example in UIExplorer. Those picker `Item`s pass in a `color` prop.

The basic picker does not pass the color prop to the picker `Item`, and there are no errors. Basic functionality is still in tact:
