Add workflow to update issue titles for clarity and specificity

[Copilot]

Summary

This PR adds a GitHub Actions workflow that will update specific issue titles to improve clarity and searchability. The workflow updates 6 issue titles with more specific descriptions that include error details, platform information, and context for when the errors occur.

Changes

1. Created a new update-issue-titles.yml workflow that updates these issue titles:

   • spawn UNKNOWN #321: "spawn UNKNOWN" → "Error: 'spawn UNKNOWN' when activating extension in VS Code on Windows"
   • The SSL connection could not be established #319: "The SSL connection could not be established" → "Plugin fails with 'SSL connection could not be established' during Azure best practices invocation"
   • Error Message: This operating system and architecture is not supported by the GitHub Copilot #318: "Error Message: This operating system and architecture is not supported by the GitHub Copilot" → "Extension reports 'operating system and architecture not supported' error"
   • github copilot not working in vscode #314: "github copilot not working in vscode" → "Error: 'EPERM' when activating GitHub Copilot for Azure extension in VS Code on Windows"
   • FAiled to install Github Copilor for Azure #297: "FAiled to install Github Copilor for Azure" → "Failed to acquire .NET runtime when installing GitHub Copilot for Azure on macOS"
   • Copilot chat tried to install Github Copilot for Azure and failed #271: "Copilot chat tried to install Github Copilot for Azure and failed" → "Failed to load System.Private.CoreLib.dll during GitHub Copilot for Azure installation on Windows"

2. Created a README.md in the workflows directory to document available workflows.

3. Added documentation in /docs/issue-title-update-instructions.md explaining:

   • The changes being made
   • How to run the workflow
   • Benefits of clear issue titles
   • Guidelines for future issue titles

How to Use

The workflow is manually triggered through the Actions tab. It requires explicit confirmation (typing "yes") to proceed with the updates to prevent accidental execution.

Benefits

• Improves issue searchability for users facing similar problems
• Provides clearer context for developers triaging issues
• Makes error patterns more visible across platform-specific issues
• Establishes a more consistent naming pattern for future issues
