Rework static hosting lab

[HenrikFricke]

In my opinion, we could improve the static hosting lab and find better (or at least explore) ways to do static hosting with AWS. I would be interested in the following questions:

• Could Amplify be interesting as a hosting platform for web applications instead of the bucket deployment?
• What are best practices for providing configurations (such as the Rest API endpoint) to the web application? Is it easy enough to showcase it?

There is also an issue with jest. If you run npx jest in lab5 it will fail since it also picks up the frontend tests. Those are not working with the jest config from the base project.
