fix: add various new scripts to glyphs [DHIS2-21946]

[BRaimbault]

Implements DHIS2-21946

Description

Open Sans does not support Arabic, Bengali, Devanagari, Ethiopic, Khmer, Myanmar, Oriya, Sinhala or Thai scripts. Lao support was added previously: #3364

• A new bundle of glyphs is generated with OpenMapTiles' fonts tool: https://github.com/openmaptiles/fonts/
• A custom bundle is created with:
  • Open Sans: https://github.com/googlefonts/opensans
  • Noto Sans: https://github.com/notofonts/notofonts.github.io/tree/main/fonts
• Total glyph payload grows from 1.90 MB to 8.24 MB (≈4.3×) due to the added script coverage

Known issues

• Khmer, Myanmar, Devanagari, Oriya, Sinhala, Bengali, Lao, Thai all show some degree of incorrect rendering for words with conjuncts, stacked marks, or vowel/tone-mark positioning (severity ranges from a visible virama mark instead of a ligature, to fully broken/disconnected conjuncts). Cause: MapLibre 5.x does not perform contextual text shaping.
  MapLibre v6.9 adds native shaping fixes, but only Khmer, Myanmar, and Devanagari are explicitly confirmed in the changelog. Bengali, Oriya, Sinhala, Lao, and Thai are not mentioned. A v6 upgrade may not resolve these and would need direct testing to confirm. The upgrade itself is non-trivial: MapLibre v6 is ESM-only (dropped CommonJS/UMD), which breaks @dhis2/maps-gl's own CJS build output and its Jest test setup.
• Arabic: fixed separately via setRTLTextPlugin in @dhis2/maps-gl. Note: if/when the MapLibre v6.9 upgrade above happens, this plugin becomes unnecessary and should be removed.
