fix(huggingface_hub): instrument OpenAI-compatible chat completions alias

[saisharan0103]

Fixes #5848.

The HuggingFace integration setup only monkeypatched InferenceClient.text_generation and InferenceClient.chat_completion. HuggingFace's OpenAI-compatible client.chat.completions.create() path is implemented on a separate chat/completions helper object, so calls through that alias did not invoke the patched InferenceClient.chat_completion method. As a result, those calls never entered _wrap_huggingface_task and missed gen_ai spans, prompt/response attributes, token usage, and error capture.

This adds a guarded patch in HuggingfaceHubIntegration.setup_once for the class method backing InferenceClient.chat.completions.create(), reusing the existing _wrap_huggingface_task wrapper with OP.GEN_AI_CHAT so the alias records the same span data as chat_completion.

The patch remains conditional via hasattr/getattr so older supported huggingface_hub versions that do not expose the OpenAI-compatible alias still import and initialize cleanly.

Unconditional contextvars import breaks 3.6

High Severity

This module now does a top-level import contextvars before the huggingface_hub availability guard. On Python 3.6, where contextvars is not in the stdlib, auto-enabling imports of HuggingfaceHubIntegration raise ImportError, which is not converted to DidNotEnable, so sentry_sdk.init() can crash even when Hugging Face is unused. Elsewhere the SDK uses ContextVar from sentry_sdk.utils for this compatibility path.
