docs: add Gonka Broker AI endpoint

Adds Gonka Broker to the AI Endpoints list as a pre-configured custom endpoint.

Gonka Broker is an OpenAI-compatible gateway to open-weight models (Qwen3, Kimi, MiniMax) served on the Gonka decentralized inference network. It exposes a public /v1/models endpoint, so the example uses fetch: true and LibreChat auto-discovers the model list.

Changes

• content/docs/configuration/librechat_yaml/ai_endpoints/gonkabroker.mdx — new provider page (mirrors the existing OpenRouter/Groq pages: API key, librechat.yaml config, user_provided option, notes)
• content/docs/configuration/librechat_yaml/ai_endpoints/meta.json — sidebar entry (alphabetical, between fireworks and groq)
• components/icons/providers/gonkabroker.tsx — provider icon (single-color currentColor path, same style as the other brand icons)
• components/icons/providers/index.ts — export the icon
• lib/icons.tsx — register the icon under the GonkaBroker key used in the page frontmatter

Verification

• pnpm build succeeds — the page prerenders at /docs/configuration/librechat_yaml/ai_endpoints/gonkabroker with the correct <title>, <h1>, meta description, and canonical.
• prettier --check and eslint pass on all changed files.

English-only; localized variants can follow via the usual translation automation.

@iamoeco is attempting to deploy a commit to the LibreChat's projects Team on Vercel.

A member of the Team first needs to authorize it.

Hi @danny-avila — gentle bump 🙏 Docs-only addition (provider page + sidebar + icon, mirrors openrouter.mdx). The Vercel preview needs a team member to authorize the deploy from my fork. Could you authorize it and take a look? Thanks for LibreChat!

Hi @berry-13 — following up 🙏 Docs-only endpoint page (mirrors openrouter.mdx); it just needs a team member to authorize the Vercel fork-preview so CI can go green. Could you authorize + take a look?
