test: update Stack trace locator for new listbox/option roles

Upstream switched ListView's ARIA roles from list/listitem to listbox/option (microsoft/playwright#40393), so the trace viewer's stack-trace sidebar no longer matches the old locator. Also align the async fixture's aria-label casing with the actual 'Stack trace' label.
