Updated RedBox screen (#22242)

Summary:
[Re: RedBox screen is a bit scary - Discussions and Proposals](https://github.com/react-native-community/discussions-and-proposals/issues/42)

Per hramos:
> The RedScreen was inspired by Ruby on Rails's error screen

> I do see the RedBox screen could be made less jarring while still successfully displaying all the information we need.

Hence jamonholmgren came up with the idea that only the header & footer of the RedBox screen could be red. This makes the content a bit more readable as well as makes the screen a little less intimidating.

Also frantic made the suggestion that since the bottom buttons are not as important, they don't need to stand out. Hence only the header of the RedBox screen which displays the error is made red.
