/**
 * Custom hook that sets up an interval and clears it after unmounting.
 * It's a way to use `setInterval` with functional components in React.
 *
 * @param callback - The function to be executed at each interval. Accepts a time delta as an argument.
 * @param delay - The duration (in milliseconds) how often to execute the callback. If `null`, the interval will be paused.
 * @returns A ref object pointing to the interval ID, which can be used to clear the interval if needed.
