winget search with empty query results in a 'No packages found' error for msstore source

Brief description of your issue

According to docs https://learn.microsoft.com/en-us/windows/package-manager/winget/search#show-all
using winget search "" --source msstore should return list of all available to install packages from msstore source, but it returns No package found matching input criteria.

It works only when application name is provided, as in example in docs winget search “Visual Studio Code” -s msstore

Without --source param it returns the same list of apps as with winget search "" --source winget

Steps to reproduce

run winget search "" --source msstore

Expected behavior

winget search -q "" should return all packages from all sources
winget search -q "" -s msstore should return all packages from msstore source

Actual behavior

winget search -q "" returns only winget apps
winget search -q "" -s msstore returns no package found

Start by reproducing winget search -q "" and winget search -q "" -s msstore on the reported environment, then trace the CLI search handling for an empty query and the msstore source. Done means an empty query returns packages from all selected sources, including msstore, instead of reporting no packages.
