Overview
Regenerates Inference Providers docs after bumping @huggingface/tasks from 0.21.7 to 0.21.8 (lockfile updated in scripts/inference-providers). All edits are in generated markdown InferenceSnippet providersMapping values—no application logic.

Vision (VLM): Adds Chat Completion (VLM) snippets for groq and nscale (meta-llama/Llama-4-Scout-17B-16E-Instruct). Task pages for chat-completion and image-text-to-text now include groq and nscale in the multi-provider VLM example. zai-org VLM example switches from GLM-OCR to GLM-4.6V-Flash.

Other example model updates: fal-ai image-to-image uses Qwen image-edit LoRA instead of FLUX.2 edit; together text-to-image uses FLUX.1-schnell instead of SDXL; hf-inference swaps featured models for feature-extraction, question-answering, and zero-shot-classification (and matching task pages).
