Update-InstalledModule

Updates all locally installed PowerShell modules to the latest versions available on PSGallery.

Features

• Automatically updates PackageManagement and PowerShellGet prerequisites before processing other modules.
• Installs to CurrentUser scope by default — no admin required.
• Optional -AllUsers switch for system-wide installs (requires elevation).
• Displays a formatted list of all modules with current vs. available versions.
• Falls back to uninstall/reinstall if a standard update fails.
• Excludes the Az and Microsoft.Graph meta-modules (to avoid reinstalling all submodules). Individual submodules (e.g., Az.Accounts, Microsoft.Graph.Users) are updated individually.

Installation
