Maintain Code Consistency With Video Lesson (Array Cardio Practice - Day 1)

[Eduardo06sp]

While watching the lesson video JavaScript Array Cardio Practice - Day 1, I noticed that problem 4 gave me unexpected results (where you calculate the total ages). I also noticed a few people in the comments were having the same issue.

So I dug deeper and noticed there were some additions to the inventors array that were not reflected in the video. One of the first rules for contributing here:

These files are meant to be 1:1 copies of what is done in the video. If you found a better / different way to do things or fixed a small bug, that is great great, but I will be keeping them the same as the videos to avoid confusing.

So for the sake of consistency and avoiding confusion for newcomers following along, I believe it's best to revert these commits.
