let's see if there's more user demand maybe

@Wauplin , this came up in a conversation with a customer recently and I think it would be great to support his. if I understand correctly, via /info users of serverless API endpoints could check which TGI version/sha an LLM like llama-3/dbrx/command-r is running on. That's quite important for debugging and understanding which recent features of TGI are supported (e.g. if guidance/function calling finally works or if the model runs on an old TGI version which is incompatible). At the moment, I'm trying to get guidance to work for llama-3 for example and I'm not sure if users can know which TGI version it is running with.

Based on this internal conversation, the TGI version/sha is only available in a private HF repo. would be great to enable users to query this information via our library.

Another example for why it's very useful for users to know the exact TGI version an endpoint is running on: (internal conversation)
