Without a landmark or widget role, aria-label on a generic <div> is
silently ignored by most screen readers (ARIA spec). Adding role="note"
gives the element an ARIA role that accepts an accessible name, making
the interlude label actually announced.
Also adds a test asserting role="note" and the matching aria-label are
both present on the same element.

Replaces aria-label="Kuratorennotiz" with m.journey_interlude_aria_label()
so screen readers get the correct label in all three supported locales.
