Github Copilot now supports the Agents.md standard, so I think we can amend the Coldbox CLI to no longer create the .github/copilot-instructions.md. I think it would be better to have a single source of truth and use Agents.md.

The Agents.md pattern is superior as well because you can nest them within your application. So, I typically have one in my project root which covers the basics of my app and I also have another one in my /tests/ folder that specifically covers my testing requirements and examples for unit, integration, and contact tests.
