`fix(litellm): pass encoding_format="float" explicitly` will break `voyage/voyage-code-3` embeddings

Issues

fix(litellm): pass encoding_format="float" explicitly in PR #144 will break embeddings with voyage/voyage-code-3, which requires base64 encoding format (error message states so)

Quick fix

I have to remove encoding_format="float" in src/cocoindex_code/litellm_embedder.py for it to work.

we need a solution to support all cases
