Update Pinget to version 0.12.0

[Gabriel Dufresne (GabrielDuf)]

What was broken

On machines where winget.exe isn't resolvable by name, the WinGet section came up empty. Pinget shells out to the system WinGet for source operations, and list propagated a failed source refresh:

Manager WinGet failed to list installed packages with exception InvalidOperationException: Pinget exited with code 1:
error: failed to run winget source command: program not found

Sources still listed fine (they answer from the store loaded at open), which is why the report shows WinGet "ready" with zero packages.

Why this PR is two lines

The fix belongs in Pinget, and it shipped there in 0.12.0
(Devolutions/pinget#44):

• WinGet is resolved past the PATH — PINGET_WINGET_PATH, the running executable's directory and the PATH exactly as before, then the App Execution Alias directory and the newest registered App Installer package. Only the last two are new, so a machine that already worked resolves the very same executable.
• A query that cannot re-mirror the sources keeps the mirror it cached earlier and reports a warning instead of failing. Commands that change sources still fail loudly, since they have to see the real source list.
• list/upgrade re-export at most every 15 minutes instead of spawning WinGet on every enumeration.
