fix: Continue traversing a non-self-closing element's children

[AdrianGonz97]

Fixes an issue where a non-self-closing element would have their children skipped when running the svelte-migrate self-closing-tags migration script.

for example:

<div>
<!-- 👇 doesn't get fixed by the migration script -->
	<i /> 
</div>
