[DOCS] Add Google Cloud TGI integration via dedicated DLCs

[alvarobartt]

What does this PR do?

This PR adds Google Cloud within the TGI Documentation https://huggingface.co/docs/text-generation-inference/main/en/reference/api_reference#cloud-providers side-by-side with the Amazon SageMaker integration.

Warning

Before merging I wanted to first clarify whether it would make sense to have a separate section within the TGI documentation for the Cloud Providers; as not sure that the Google Cloud integration fits within the HTTP API Reference page? Maybe you can help clarify a bit better @nbroad1881

My 2 cents:

In Reference > API Reference > HTTP API Reference > OpenAI Messages API > Cloud Provider, I would just point to https://cloud.google.com/vertex-ai/generative-ai/docs/multimodal/call-vertex-using-openai-library#supported-model-garden-models

What you wrote fits a generic introduction about using TGI on GCP. I think it's valuable to add it to the TGI doc but this is not the right place. It could be in Tutorials or Getting Started with simple pointers to the existing doc in https://huggingface.co/docs/sagemaker/en/index for AWS and https://huggingface.co/docs/google-cloud/en/index for Google Cloud.

Agree @pagezyhf, also the AWS SageMaker section there is also covering deployment + inference, which may be out of the scope of the section, right?

Yes that's right, that's why I also think that we should maybe have a dedicated entry for those with brief introduction plus pointers to the actual documentation pages we host separately

Thanks for the replies @pagezyhf 🤗 WDYT about those @nbroad1881?
