docs: sync OpenRouter LLM supported model list with current node options

[lin-bot23]

Summary

The OpenRouter LLM node's model dropdown gained several models that were missing from the Supported models table on the OpenRouter LLM page. The pricing table already lists these models; this PR brings the page's model list in sync.

Added rows (verified against node source):

• anthropic/claude-opus-5, claude-opus-4.8, claude-fable-5, claude-sonnet-5, claude-haiku-4.5 (ComfyUI PR #16188-era OpenRouter expansion follow-ups)
• openai/gpt-5.6-sol/-sol-pro, -terra/-terra-pro, -luna/-luna-pro
• x-ai/grok-4.5
• moonshotai/kimi-k3

All vision slots, video support, and extra options mirror the node's _ModelSpec entries. Applied to EN, zh, ja, ko.
