Fetch latest package download URLs from winget-pkgs repository

[Copilot]

Automatically generates PackageFeed.xml with latest download URLs for Chrome, Edge, and Adobe Reader from microsoft/winget-pkgs during GitHub Pages builds.

Changes

• src/wingetfeed.cs: New .NET 10 file-based tool that:

  • Queries GitHub API to find latest package versions in winget-pkgs manifests
  • Parses YAML installer manifests using YamlDotNet
  • Generates XML feed with package ID, version, and installer URL
  • Uses GITHUB_TOKEN for API authentication to avoid rate limits

• .github/workflows/publish.yml: Integrated tool into build pipeline between catalog generation and HTML transformation

• Documentation: Added docs/WinGetPackageFeed.md with usage details and XML schema

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)

<issue_title>winget-pkgs 리포지터리와 연계한 최신 패키지 피드 다운로드 URL 획득하기</issue_title>
<issue_description>GitHub Pages 빌드 시 https://github.com/microsoft/winget-pkgs.git 리포지터리의 master 브랜치를 체크아웃하여 Chrome, Edge, Adobe Reader 등의 피드를 가져와서 최신 버전의 다운로드 URL을 별도 XML 파일로 만들어 publish 하도록 구현한다.

Chrome을 수동 설치해야 하는 경우, Adobe Reader 익스텐션 자동 설치 구현을 위해 이 기능을 구현하고자 한다.
