Summary

Adds Goldsky Edge RPC to the RPC providers overview and provider sections. Documents HTTPS JSON-RPC, caching, usage dashboards, and the absence of WebSocket support. Mainnet uses chain ID 988; Testnet uses 2201.

Refreshes the Chinese and Korean RPC providers pages using the translation pipeline and its model review pass. Restricts style-report comments and suggestions to same-repository PRs so fork PRs can finish the style job with read-only tokens. Linting and failure enforcement still run.

Validation

• npm run check passed under Node 22 after integrating current main, including the three-locale build.
• i18n:check: 0 missing. Both RPC providers translations have current source hashes; remaining stale warnings concern unrelated pages.
• Checked translated links, inline code, section counts, and endpoint values against English.
• Verified Goldsky Mainnet and Testnet return chain IDs 0x3dc and 0x899, plus block numbers.
