The Weblate merge added a values-ar translation (~50% complete, RTL —
the app already declares supportsRtl). Add the matching <locale> line so
Arabic is selectable in both the in-app picker and the system per-app
language settings. Russian and Portuguese stay out for now: at 12% and
<1% they're below the usable bar (the lowest currently-offered language,
zh-CN, sits at ~24%).
