Migration : Error migrating parametized slots

[adiguba]

Describe the bug

I found some errors when migrating parametized slots.

Constant values ​​are not reported correctly, and produce an error :

-<slot name="header" title="Hello World" />
+{@render header?.({ title: Hello World, })}

Dynamic values ​​are wrapped in an additional object :

<script>
+	/** @type {{header?: import('svelte').Snippet<[any]>}} */
+	let { header } = $props();
	let value = "Hello World";
</script>
-<slot name="header" title={value} />
+{@render header?.({ title: {value}, })}

=> header?.({ title: {value}, })} might be header?.({ title: value, })}

Also: is it normal that slots are converted to snippets in the component, but not in the code that uses it?
