Add winget machine scope install tests

[github-actions]

Script Analysis

• Added new GitHub workflow for machine scope installation testing
• Exported constants MACHINE_INSTALL_DIR and USER_INSTALL_DIR in common.nu for better reusability
• Updated winget-install.nu to handle both user and machine scope installations
• Improved scope handling with conditional logic for different installation paths
• Maintained consistent use of Nushell string interpolation and path handling

Security Review

• ✅ Environment variables are properly managed (GITHUB_TOKEN)
• ✅ No direct command injection risks identified
• ✅ Proper use of winget flags (--accept-source-agreements, --disable-interactivity)
• ⚠️ Consider adding input validation for the --scope parameter in main function

Optimization Suggestions

• 🔄 Consider using match instead of if for scope handling for better readability
• 📦 Could potentially consolidate the installation checks into a single function with scope parameter
• ⚡ Might benefit from parallel execution of different scope tests in CI
