Fix defect in Enumerable#many introduced in rails/rails@d862dff

This changed `many?` to yield with `element, *args`. The causes elements that are arrays to be destructured which can lead to defective behaviour. Since the introduction of `element, *args` was for readability purposes, we can just use `*args` instead and get the same behaviour without the defect.
