deprecated an removed models still appearing in api reference

[snova-jorgep]

We have deprecated and removed the sambaverse product several months ago, those changes were reflected in the code in which there is no anymore an llm class implementation for sambaverse hoy ever in API reference documentation this is still appearing:

https://api.python.langchain.com/en/latest/community/llms/langchain_community.llms.sambanova.Sambaverse.html

this should be removed, I wonder why is been kept in the API reference generation if the implementation doesn't exist anymore
