[BUG] Georgian language is missing from the GUI language selector #1472

Describe the bug

The Georgian translation already exists in src/gui/locales/ka-GE.json, and ka-GE is included in gui.rs locale tests. However, Georgian is missing from the language dropdown in src/gui/index.html, so users cannot select it in the application.

Expected behavior: Georgian (ქართული) should be available in the GUI language selector.

Used bbox area

Not applicable — this is a GUI issue, unrelated to map generation.

Arnis and Minecraft version

• Arnis: 3.4.0
• Operating system: Windows 11
• Minecraft version: Not applicable.

Screenshots

Not applicable. I can provide screenshots if needed.

Additional context

The translation files are already present, so no additional translation work should be necessary.
