Add all-contributors to automatically recognize repository contributors

[Copilot]

This PR implements the all-contributors project to automatically recognize and display contributors in the README.md file, making it easy to acknowledge community contributions of all types.

What's Added

Contributors Recognition System:

• Added all-contributors CLI tooling with proper configuration
• Contributors are displayed in a visual gallery with avatars and contribution types
• Supports multiple contribution types: code, documentation, ideas, bug reports, design, and more
• Added contributors badge in the header showing the current contributor count

Integration with Existing Build System:

• Modified update-readme.js to include the contributors section in the footer
• Contributors section is automatically preserved when README is regenerated
• Works seamlessly with the existing README validation workflow

Automation & Workflows:

• Added GitHub Actions workflow that runs weekly to check for new contributors
• Manual trigger available for immediate contributor updates
• Automated pull request creation when contributors are detected

Documentation & Setup:

• Created package.json with all-contributors scripts for easy management
• Updated CONTRIBUTING.md to explain the contributor recognition process
• Added usage instructions and examples for maintainers

Usage Examples

For maintainers to add contributors manually:

# Add a contributor for code contributions
npm run contributors:add -- username code

# Generate the contributors list
npm run contributors:generate

For automated detection:
The weekly GitHub Actions workflow will automatically detect new contributors and create PRs to add them.

Technical Details

• Uses all-contributors specification v6.26.1
• Configured for the github/awesome-copilot repository
• Avatar size: 100px for optimal display
• Contributors per line: 7 for clean layout
• No auto-commit to maintain manual control over changes

The implementation includes Christophe Peugnet (@tossnet) as the first recognized contributor for code contributions, and the system is ready to automatically recognize future contributors as they make contributions to the project.

Fixes #205.

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:

• https://api.github.com/repos/github/github/awesome-copilot/contributors
  • Triggering command: node /home/REDACTED/work/awesome-copilot/awesome-copilot/node_modules/.bin/all-contributors check (http block)
• https://api.github.com/users/tossnet
  • Triggering command: node /home/REDACTED/work/awesome-copilot/awesome-copilot/node_modules/.bin/all-contributors add tossnet code (http 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)
