feat/idea: create a mini quiz for each chapter

[glaucia86]

We can gamify the experience with small challenges that users need to solve within the README in each chapter.

• At the end of the lesson, add a quick quiz to test knowledge:

## 🧩 Quick Challenge!
What was the main architectural challenge that Dinocrates faced?
- [ ] Lack of materials
- [ ] Navigation issues near the coast
- [ ] Political instability

• This can be combined with GitHub Discussions to encourage conversations.

✅ Impact: Makes learning more interactive and promotes knowledge retention.
