Add Korean translation for Infrastructure section (first half)

[mintlify]

Summary

Added Korean translations for the first half of the Infrastructure section pages:

• Infrastructure overview (ko/infra/index)
• Interact with nodes subsection:
  • Overview (ko/infra/interact-node/index)
  • CLI (ko/infra/interact-node/command-line)
  • gRPC (ko/infra/interact-node/grpc)
  • Go (ko/infra/interact-node/go)
  • REST (ko/infra/interact-node/rest)
• Running a node (ko/infra/run-node)
• Setting up keyring (ko/infra/set-up-keyring)
• Joining a network (ko/infra/join-a-network)
• Cosmovisor setup guide (ko/infra/cosmovisor)
• Upgrading your node (ko/infra/upgrade-node)

Translation approach

• Maintained technical documentation tone
• Preserved technical terms (injectived, gRPC, Cosmovisor, keyring, etc.)
• Kept same document structure as English docs
• Updated navigation in docs.json with Korean group name "인프라"
