winget reports pinned packages during update, but pin list is empty.

Relevant area(s)

WinGet CLI

Relevant command(s)

winget pin, winget upgrade

Brief description of your issue

Running winget update --all reports packages are pinned. winget pin list reports no pins are configured. These are mutually exclusive and this is an inconsistent state.

Steps to reproduce

Note for this test case I have never used the winget pin feature to manually pin any packages.

PS C:\Users\User01> winget update --all
No installed package found matching input criteria.

The following packages have an upgrade available, but require explicit targeting for upgrade:
Name    Id              Version  Available Source
-------------------------------------------------
Discord Discord.Discord 1.0.9242 1.0.9243  winget
1 package(s) are pinned and need to be explicitly upgraded.
PS C:\Users\User01> winget pin list
There are no pins configured.
PS C:\Users\User01>

Expected behavior

winget should be consistent in managing pins.

Actual behavior

winget is inconsistent in managing pins.

Environment

Start by reproducing the reported behavior with winget update --all and winget pin list on the WinGet CLI version and Windows environment shown. Trace how the winget pin and winget upgrade commands obtain pin state, then verify that an empty pin list cannot cause an upgrade to be reported as pinned.
