d2c86df1 - fix(huggingface): switch integration test provider to together (#35525)

fix(huggingface): switch integration test provider to together (#35525) Switch the `TestHuggingFaceEndpoint` serverless inference provider from `sambanova` to `together` for `Llama-3.3-70B-Instruct`. Sambanova doesn't support `tool_choice: "any"` (needed by `test_structured_few_shot_examples` and `test_unicode_tool_call_integration`) and doesn't return `usage_metadata` in streaming responses.
