Svelte 5: Actions from object properties are not properly escaped

[brunnerh]

Describe the bug

Actions can be defined on objects and just used via use:object.property, if the property is not a valid JS symbol, it has to be escaped which right now does not happen.

Reproduction

<script>
	const a = { 'set-color': (node, c) => node.style.color = c };
</script>
<span use:a.set-color={'red'}>Text</span>

v4 ✔️
v5 ❌

Compiled bit of code:

$.action(span, ($$node, $$props) => a.set-color($$node, $$props), () => 'red');
