Update no internal modules with exports

[adjerbetian]

Resolves #1481

About the breaking change

In the ticket it was suggested to add an option for this behavior. Do you still want this rule behind an option? This behavior with the export feels so natural to me that I would feel strange if it wasn't the default behavior.

Changelog

I update the documentation, but I didn't know how to update the changelog. I wouldn't be against some guidance or help here 😊.

Step down rule

I hesitated to clean the code in /src/rules/no-internal-modules.js to use the step down rule, but I don't want to impose my tastes on this. Do you want me to do it?

@ljharb Can you give me your opinion on this?

I agree; this feels like a bugfix.
