Suggest integrating Cohere Embedding modell, especially the

"embed-multilingual-v3.0" as it supports over 100 languages, and the english model could be implemented at the same time. (https://docs.cohere.com/reference/embed)

This makes sense to let Dify diversify across many languages on the embedding side, also it should be an easy implementation based that Cohere is the main reranker.
