`Phaser.Math.RND.Pick` and `Phaser.Math.RND.WeightedPick` should use `ArrayLike` interface

Version

• Phaser Version: 3.90.0
• Operating system: Ubuntu 24.04 LTS (irrelevant)

Description

Currently, Phaser.Math.RandomDataGenerator.Pick and its weighted counterpart require the arguments passed in to be mutable arrays.
Since these functions do not mutate their arguments (and, moreover, do not require anything but numeric index support and a .length property), they should use the more general ArrayLike<T> interface instead.

At the moment, attempting to pass in readonly arrays or array-like objects such as TypedArray will produce type errors despite working perfectly well at runtime.

Example Test Code

import Phaser from "phaser";
const nums = [1, 2, 3] as const;

const randomNum = Phaser.Math.RND.pick(nums);
// type errors since `nums` is readonly, despite running perfectly fine

Additional Information

Trivial to fix; I will create a PR shortly.

Start at the Phaser.Math.RandomDataGenerator.Pick and weighted-pick entry points named in the issue, then inspect their type definitions. Verify that readonly arrays and TypedArray-like inputs are accepted while preserving the existing runtime behavior; use the provided TypeScript example as the completion check.
