Add Arabic (ar_SA) language pack

[kaluaim]

Summary

• Adds an Arabic (ar_SA) language pack entry to LanguagePacksJson
• The pack is built from the Vazirmatn font (SIL OFL 1.1), chosen as the default Arabic font in the discussion on applib: treat Arabic diacritics as transparent for cursive joining PebbleOS#1622
• hardware: null so it applies to all supported platforms
• .pbl hosted as a release asset on my PebbleOS fork: https://github.com/kaluaim/PebbleOS/releases/tag/ar_SA-v1

Background

This accompanies the Arabic shaping/RTL rendering fixes merged into PebbleOS (most recently coredevices/PebbleOS#1622), and was requested by @ericmigi in this comment. Tested on a Core Time 2.

Hi @ericmigi @sjp4 👋 Friendly nudge on this one — could it be merged to unblock Arabic users? Happy to adjust anything if needed. Thanks!

hardware: null so it applies to all supported platforms

Does this work on all hardware? (e.g. OG Pebbles). The previous json had specific platforms listed because the pack would not work on others

@sjp4 I used hardware: null to match other language packs, and because the per-hardware entries never showed in the app — looks like 5d31045 fixes that (unreleased, so unverified). The pack didn't render on a Time Steel (elbbeP firmware), so I've restored the 7 hardware entries; only the URL and native العربية name change now. Sideload-tested on Core 2 Duo and Core Time 2; in-app download still unverified.
