i18n: Turkish "Open" is the verb (Aç); the Arc tool's open arc keeps Açık (#4564)

The Turkish catalog translated the bare "Open" as the adjective (Açık), so the Home screen's Open button and the History panel's first row read "open" rather than "open it". The Arc tool's Type choice, where Open is the adjective, now looks its labels up in a "shape" context (falling back to the plain row in the other languages), and Turkish gives it Açık there.
