4893 svelte/no-unused-props errors.

For instance, this file:

<script lang="ts">
	import type { SVGAttributes } from "svelte/elements"
	import { SvgIcon, type IconProps } from "."

	let props:  {
	name?: string
	color?: string
	size?: number | string
	strokeWidth?: number | string
	absoluteStrokeWidth?: boolean
	class?: string
} & SVGAttributes<SVGSVGElement>= $props()
</script>

<SvgIcon viewBox="0 0 512 512" {...props}>
