test(dynamic-import): fix multiline test

[bluwy]

Description

I messed up the test added in #9314 😅

This should make the multiline test work correctly. Otherwise this part

vite/playground/dynamic-import/nested/index.js

Lines 87 to 94 in 44944d0

	// prettier-ignore
	import(
	/* this messes with */
	`../alias/${base}.js`
	/* es-module-lexer */
	).then((mod) => {
	text('.dynamic-import-with-vars-multiline', mod.hello())
	})

causes a runtime error in the browser.
