feat: Add GitHub Packages support for NuGet distribution

- Add RepositoryUrl to project file for GitHub integration
- Configure workflows to publish to both NuGet.org and GitHub Packages
- Add packages:write permission to workflows
- Update README with GitHub Packages installation instructions
- Add --skip-duplicate flag to prevent duplicate package errors

Now packages will be available at:
- NuGet.org: https://www.nuget.org/packages/DotnetDevKR.TailwindCSS/
- GitHub Packages: https://github.com/dotnetdev-kr/DotnetDevKR.TailwindCSS/packages
