Replace copy/paste instructions with simple reference examples for GitHub issue creation

[Copilot]

This PR eliminates the need for users to copy/paste large blocks of content when creating GitHub issues for template setup and updates. Instead, users now create issues with simple 2-3 line examples that reference template files, allowing GitHub Copilot agents to read requirements dynamically.

Problem

Previously, users were instructed to copy/paste complex markdown blocks (30+ lines) when creating GitHub issues:

**GitHub Copilot**: Please help me update my ioBroker Copilot instructions template to the latest version while preserving all custom sections.

## Task
Update `.github/copilot-instructions.md` using this prompt:

"Merge the ioBroker template from https://github.com/DrozmotiX/ioBroker-Copilot-Instructions/blob/main/template.md with my existing .github/copilot-instructions.md. 

REQUIREMENTS:
1. Preserve ALL [CUSTOMIZE] sections exactly as they are
2. Keep all project-specific context not already covered in the standard template
[...continues for many more lines...]

This approach was prone to copy/paste errors, difficult on mobile devices, and required manual maintenance when requirements changed.

Solution

Users now create issues with simple references that let Copilot agents read template files dynamically:

New Repository Setup:

Title: 🤖 Setup ioBroker GitHub Copilot Instructions

GitHub Copilot: Please help me set up GitHub Copilot instructions for my ioBroker adapter repository using the template from:
templates/initial-setup-automation.md
