CLI: Add `nodeinfo` command using Optique

[sij411]

Summary

Add nodeinfo command to cli with Optique instead of cliffy.

Problem

For now, nodeinfo.ts has an empty function only. It should be implemented to run as same as original cli with cliffy does, but with Optique. Also it should be cross-runtime so existing Deno API should be replaced to Node API.

Proposed Solution

1. Add nodeinfo.ts
