Finite Math Cohort H5P content

@ashley.segalla @rbroussard3 @tspahn Hi all, Ashley added dropdown content for many of the exercises in Chapter 1. I’ve gone through and added H5P content for the exercises she didn’t do in chapter 1. Jared did Chapter 2. So, now every Exercise in chapter 1 and 2 has either a dropdown exercise or an H5P exercise. Section 3.1 is done as well. I will look into Chapter 3 a little more tomorrow.
