refactor: CRA exemple without CRACO

[neysimoes]

CRACO don't support CRA 5 yet and searching for maintainers.

However, CRA still does not have a way of working with Module Federation.

This solution:

• Does not require any external dependency on the CRA
• Does not need to be ejected
• Small code implementation
