Pull request overview

This pull request introduces cross-platform and cross-browser matrix testing for integration tests. The key objectives are to enable comprehensive testing across Windows, Linux, and macOS operating systems using Chromium, Firefox, and WebKit browsers, and to properly separate integration tests from unit tests in the CI/CD pipeline.

Changes:

• Updated npm registry configuration across multiple packages to use the public npmjs.org registry
• Added matrix testing strategy to GitHub Actions workflow for integration tests across 3 operating systems and 3 browsers (9 total combinations)
• Enhanced PlaywrightSession to support browser selection via parameter or environment variable
• Added [Trait("TestType", "Integration")] to integration test classes to enable test filtering
• Removed Linux-specific test skipping logic from IntegrationTestFactAttribute
• Updated deployment configuration with new Azure Container Registry secret names
