Support for codestral/embedding API kind

[Silzinc]

Please describe the feature you want

Mistral AI made an embedding API for codestral-embed (actually they made another one for mistral-embed, but I don't expect it to be any relevant compared to codestral-embed for this project). This contradicts the tabby docs if I'm not mistaken.

Would it be possible to support a new codestral/embedding (or mistral/embedding) API kind for this?

Additional context

I stumbled on this while trying to configure codestral-embed in tabby.

Here is my current (failing) config for this model:

[model.embedding.http]
kind = "openai/embedding"
model_name = "codestral-embed"
api_endpoint = "https://api.mistral.ai/v1"
api_key = "my-key"

Here, I have been using the openai/embedding API although it is not exectly the one expected by the model. Upon connection, I obtain this error:

Error 422: {"detail":[{"type":"model_attributes_type","loc":["body"],"msg":"Input should be a valid dictionary or object to extract fields from","input":"{\"input\":[\"hello Tabby\"],\"model\":\"codestral-embed\"}"}]}

Besides, this works perfectly fine in my terminal:

curl -X POST "https://api.mistral.ai/v1/embeddings" \
           -H "Content-Type: application/json" \
           -H "Authorization: Bearer $MISTRAL_API_KEY" \
           -d "{\"input\": [\"hello Tabby\"], \"model\": \"codestral-embed\"}"

Thank you in advance!
