Docs site out of date: LLMGateway "Ask AI" tab merged but not live

### Summary The LLMGateway provider tab in the **Ask AI** section was merged into `dev` via #3318, but the live docs site doesn't show it yet. ### Details - Source on `dev` already includes the tab: `apps/docs/content/docs/(framework)/integrations/llms.mdx` has `<Tabs items={['AI SDK', 'LLMGateway', 'Inkeep AI']}>` with the `npx @fumadocs/cli add ai/llmgateway` install command. - Live page https://www.fumadocs.dev/docs/integrations/llms#ask-ai still only shows **AI SDK** and **Inkeep AI** tabs. This looks like a deployment lag — the production build predates #3318. ### Request Could you redeploy `fumadocs.dev` from the current `dev` branch so the LLMGateway tab appears on the live page? Related follow-up: #3319 (documents the optional `LLM_GATEWAY_MODEL` env var in the same tab).
