Errors are not moved when using `type $$Props`

[dummdidumm]

Describe the bug

This code

language-tools/packages/language-server/src/plugins/typescript/features/DiagnosticsProvider.ts

Lines 132 to 136 in caf179a

	const is$$PropsError =
	isAfterSvelte2TsxPropsReturn(
	fragment.text,
	fragment.offsetAt(diagnostic.range.start)
	) && diagnostic.message.includes('$$Props');

is not working, in other words not moving the error, when someone uses type $$Props = .. because the word $$Props doesnt show up then.

Reproduction

<script lang="ts">
	interface ItemData {
		x: number;
		y: number;
	}

	type $$Props = ItemData;

	export let x;
	export let y:string;
</script>
