feat (docs): updated Sarvam official community provider

[rajatsandeepsen]

Background

Previous Sarvam provider package was unofficial and old #6079

But this one is officially approved by Sarvam DevRel team & @kurianbenoy-sarvam

From now on, we'll make sure a regular and up-to-date changes to this community provider package.

Summary

Added more API support for Sarvam, including

• Chat completion
• Text-to-Speech
• Speech-to-Text
• Language identifications
• Translation
• Transliterate
• Tool Calling

Future Work

Latest sarvam-m model isn't trained on native tool calling feature (aka JSON mode). So we simulate this with added prompt engineering technique.

Soon team Sarvam will release next new model with complete OpenAI API support.

Also we're working on the future ai-sdk v5 support too.

Note

India has two Official Languages (Hindi and English) and 22 Scheduled Languages + almost 1,369 unofficial languages

So provider specific arguments options like source/target language code are super important as modelId params. So we put them inside provider instances functions, instead of using providerOptions: { sarvam: { } } to bring more type strictness & type completion for developers
