chore(ci): update GitHub Pages documentation workflow

Simplify and modernize the documentation deployment process. Replace separate build/deploy jobs with a single publish-docs job using the latest actions. Update actions/checkout to v4, actions/setup-dotnet to v4, and switch to actions/deploy-pages for deployment. Add proper permissions and concurrency settings for GitHub Pages.
