reorder Scripting test your skills for consistency

[chrisdavidmills]

Description

I got some feedback that the ordering of the "Test your skills" articles has become confusing since the last update. Specifically, in some of the tests, the "solution" live sample appears before the "starting state" live sample, so it is unclear which one to click on to start the test.

To remedy this, I have decided to go through all the "Test your skills" articles and make the structure as consistent as possible throughout, fixing the above issue in the process.

This PR in particular updates the structure of the Dynamic scripting with JavaScript "Test your skills" articles.

Note: Not all of the tests show the finished state of the example. I have elected not to show it in cases where the before and after rendering look no different, where the final rendering gives away the answer, and where the question is freeform so there is no single answer.
