[Feature Request] Add Vietnamese (vi) language support for navigation

Feature Request: Vietnamese Language Support

Summary

Request to add Vietnamese (vi) language support to Mintlify's existing language navigation feature, following the same pattern as currently supported languages.

Current State

Mintlify currently supports 15 languages for navigation localization:

• Arabic (ar), Chinese (cn/zh-Hant), English (en), French (fr), German (de)
• Indonesian (id), Italian (it), Japanese (jp), Korean (ko), Portuguese (pt/pt-BR)
• Russian (ru), Spanish (es), Turkish (tr)

Business Justification

• Developer Population: Vietnam has 500,000+ developers and a rapidly growing tech ecosystem
• Market Growth: Vietnam's software development market is expanding at 15%+ annually
• Regional Gap: Vietnamese is missing despite neighboring countries (Indonesia, Korea) being supported
• Documentation Accessibility: Would enable Vietnamese companies and open-source projects to serve local developers effectively

Technical Implementation

Based on the existing language structure in docs.json, this would involve:

{
  "navigation": [
    {
      "group": "Getting Started",
      "pages": ["introduction", "quickstart"],
      "language": "vi"
    }
  ]
}
