Update to $props() for legacy <svelte:self>

[jaminwebdev]

Describe the bug

https://svelte.dev/docs/svelte/legacy-svelte-self shows old prop declaration syntax:

<script>
	export let count;
</script>

{#if count > 0}
	<p>counting down... {count}</p>
	<svelte:self count={count - 1} />
{:else}
	<p>lift-off!</p>
{/if}

Should probably update to $props()

This is in the legacy documentation, and as such should use Svelte 4/3 syntax.
