Fix PHPStan @return unused type return.type on RectorInterface

[samsonasik]

On latest PHPStan 2.1.30, using Interface::* seems mark as all must be returned, but not support partial of it, so use int over it.

Added comment note for how return int works.

All checks have passed 🎉 @TomasVotruba I am merging it ;)

I prefer to keep original list, as now any int value can be returned by PHPStan, which is not true.
Could you revert this one?

Ok, the rule classes itself then need update to add @return for specific constant then, eg:

    /**
     * @param StmtsAwareInterface $node
+    * @return null|Node|NodeVisitor::DONT_TRAVERSE_CHILDREN
     */
    public function refactor(Node $node): null|Node|int

I will revert this and update rule classes

I created PR to use NodeVisitor::* on RectorInterface::refactor(), then update its rules @return to use its constant at PR:
