Changelog

Here's what's going to be different in the next version of the testing-react-apps workshop (you can find all these changes in the `next` branch until the videos are re-recorded):

- Everything is TypeScript. There's a new script you can run to remove the TypeScript automatically if you want: `./scripts/remove-ts`.
- General improvements to the workshop content based on feedback from learners
- Exercises 1, 3, 4, 6, and 8 all had instruction improvements based on feedback
- Exercise 6 (mocking) swapped the extra credits to make it iterate a little bit better.

Review the `next` branch and the listed workshop changes first. The issue names no file, test, or concrete remaining task, and it does not provide enough information to verify what work, if any, would be done.
