Brief description of your issue

Install-WinGetPackage downloads the package installer for the package, even when the package is already up-to-date. winget install does not do this.

Steps to reproduce

• Update-WinGetPackage Microsoft.PowerShell
• Re-run Update-WinGetPackage Microsoft.PowerShell
  • Notice how a download progress bar appears
  • Compare with winget install Microsoft.PowerShell

Expected behavior

It first checks if the package is up-to-date, and only downloads the installer if it is not.

Actual behavior

It always downloads the installer.

Start by reproducing the behavior with Update-WinGetPackage Microsoft.PowerShell twice and compare it with winget install Microsoft.PowerShell. Trace the WinGet CLI and PowerShell Module paths involved in package state checks and downloads; done means an up-to-date package is detected before its installer is downloaded, while an outdated package still installs normally.
