Transform minimal README into comprehensive VS Code reference documentation

[Copilot]

This repository exists as a reference to the official Microsoft VS Code repository. The README was a 2-line placeholder containing only the repository name and URL.

Changes

• Restructured README.md with organized sections:

  • Official repository links (GitHub URL and clone command)
  • VS Code overview and key features
  • Resource links (website, docs, downloads, marketplace, releases)
  • Getting started instructions
  • Contributing and license references

• Added clarity that this is a reference repository, not the actual VS Code codebase

The README now serves as a useful landing page that directs users to official VS Code resources while providing context about the project.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• code.visualstudio.com
  • Triggering command: curl -s -o /dev/null -w %{http_code} REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
