	*
	 * Wrapper around `CollectionService` that provides a list of `Instance` under the given `tag`.
	 *
	 * This list is updated as `Instance` are added and removed. You can also cast the `Instance` to the expected type.
	 *
	 * ```ts
	 * const zombies = useTagged<ZombieModel>("zombie");
	 * ```
	 *
	 * @param tag The `CollectionService` tag name to filter against.
	 * @returns A stateful list of `Instance` matching the provided `tag`.
	 * @template T An optional subtype of `Instance` to cast the tagged children to.
