Fix Incorrect Syntax in Array Destructuring Lesson

Issue

The array destructuring lesson on learn-js.org contains incorrect syntax for renaming variables during array destructuring. It uses object destructuring syntax (e.g., let [two: positionZero, three: positionOne] = numbers;), which is invalid in array destructuring.

Problem Code

let numbers = ['2', '3', '7'];
let [two: positionZero, three: positionOne] = numbers;

console.log(positionZero); // This results in an error
