Add Text Embeddings Inference (TEI) tag & snippet
This PR adds the text-embeddings-inference tag into the README.md metadata to both let the community know that they can deploy Alibaba-NLP/gte-multilingual-base with Text Embeddings Inference (TEI), but also to improve discoverability within the Hub. Additionally, this PR also includes a snippet within the README.md under the "Usage" section on how to deploy Alibaba-NLP/gte-multilingual-base and send a request to the /v1/embeddings OpenAI-compatible endpoint.
Note that before TEI 1.6.1 in order to deploy Alibaba-NLP/gte-multilingual-base with TEI, one had to provide the --revision refs/pr/7 as per https://huggingface.co/Alibaba-NLP/gte-multilingual-base/discussions/7 which is no longer required since TEI 1.6.1, since this model is handled within TEI as per https://github.com/huggingface/text-embeddings-inference/pull/538.
