In the Street Eats codealong, refactor props

[twant]

In https://github.com/upperlinecode/CS-and-the-City-Curriculum/blob/master/react/props-jsx.md, props are passed by breaking down a much larger object and passing each part of it to a separate prop.

In practice, this is an example of unnecessary decoupling, and does not model best-practices to students. With that in mind, the end challenge, in which the reviews object is passed to a single prop and then broken down within the component constructor needs to be elevated in importance. At a minimum, its visual importance in the markdown file should be increased.
