docs: Update Module 2 to use GitHub Codespaces consistently

[RayPops]

📝 Summary

This PR updates Module 2 of the "Using GitHub Copilot for Azure to Deploy to Cloud" workshop to use GitHub Codespaces consistently, aligning with the Codespaces-first approach established in Module 1.

🎯 Problem

Module 1 instructs users to open a GitHub Codespace for the workshop, but Module 2 switches to local development instructions ("Create a new folder on your local computer"). This inconsistency:

• Creates confusion for workshop participants
• Requires users to have local development tools installed
• Breaks the seamless cloud-based learning experience
• May cause issues for users on restricted corporate machines

✨ Solution

Updated Module 2 to:

1. Continue in Codespaces - Instructions now assume users are continuing from their Module 1 Codespace
2. Use terminal-based folder creation - Replaced GUI-based folder creation with command-line instructions
3. Added consistent formatting - Aligned with Module 1's structure including:
   • Header metadata (Who is this for, What you'll learn, etc.)
   • Emoji section markers for visual navigation
   • Prerequisite reading section
   • Additional resources section
4. Improved clarity - Added tips, notes, and troubleshooting guidance
5. Fixed relative links - Updated module links to use relative paths

📋 Changes Made

Section	Change
Header	Added structured metadata matching Module 1 format
Prerequisites	Clarified Codespace continuation requirement
Step 1	Replaced local folder creation with terminal commands
Steps 2-5	Restructured for clarity with consistent formatting
Troubleshooting	Added dedicated troubleshooting section
Resources	Added additional learning resources

🧪 Testing

• Verified all terminal commands work in GitHub Codespaces
• Confirmed all image links are accessible
• Tested relative links to other modules
• Validated Markdown rendering on GitHub

✅ Checklist

• Documentation follows existing style guidelines
• All links are valid and accessible
• Instructions tested in GitHub Codespaces environment
• No breaking changes to other modules
• Consistent formatting with Module 1
