ReactiveDate.toLocaleString ignores arguments

[brunnerh]

Describe the bug

It just don't care.

Also applies to toLocaleDateString & toLocaleTimeString.

Reproduction

<script>
	import { Date as ReactiveDate } from 'svelte/reactivity';

	const regular = new Date();
	const reactive = new ReactiveDate();
</script>

{regular.toLocaleString()} <br>
{regular.toLocaleString(undefined, { month: 'short' })} <br>
{regular.toLocaleString('fr-FR')} <br>
{regular.toLocaleString('fr-FR', { month: 'short' })} <br>
<br>
{reactive.toLocaleString()} <br>
{reactive.toLocaleString(undefined, { month: 'short' })} <br>
{reactive.toLocaleString('fr-FR')} <br>
{reactive.toLocaleString('fr-FR', { month: 'short' })} <br>

Lines 69 to 89 in 3f7fcf9

	for (const method of read) {
	// @ts-ignore
	proto[method] = function () {
	get(this.#raw_time);
	// @ts-ignore
	return date_proto[method].call(this);
	};
	}
	for (const method of write) {
	// @ts-ignore
	proto[method] = function (/** @type {any} */ ...args) {
	// @ts-ignore
	const v = date_proto[method].apply(this, args);
	const time = date_proto.getTime.call(this);
	if (time !== this.#raw_time.v) {
	set(this.#raw_time, time);
	}
	return v;
	};
	}

Presumably the read methods we define here will also need to accept ...args like the write ones do.
