Winget not work if used in a Network with CISCO Umbrella

Brief description of your issue

Discussion: https://github.com/microsoft/winget-cli/discussions/1903#discussion-3855105

If I run winget list it spins shortly and then the command line turns blue, without any output.

If I remove this source Winget works. https://winget.azureedge.net/cache

I suppose a problem with a pinned Certificate

Steps to reproduce

Use Cisco Umbrella, or Is suppose a kind of SSL MITM

Expected behavior

Best case:
SSL Certificate Error. We suppose a Man-in-the-middle attack If you wish to procceed type "yes"

Second best:
SSL Certificate Error. We suppose a Man-in-the-middle attack If you wish to procceed enter "winget settings" and add "SSL": {"AllowMITM":TRUE}

Worse case:
Windwos Dialog Popup: Error XXXXX do you want proceed? 😉

Actual behavior

Command prompt turns blue

Start by reproducing winget list with Cisco Umbrella enabled and the https://winget.azureedge.net/cache source configured; review diagnostics under %LOCALAPPDATA%\Packages\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\LocalState\DiagOutputDir. Done means the command reports a clear certificate or MITM-related error instead of turning the command prompt blue, while preserving normal behavior when the source is removed.
