Packages from "msstore" source aren't visible in `list` or `export`

Brief description of your issue

When I run winget search for an MS Store app, all the apps from the store show IDs that are just a sequence of numbers and capital letters of fixed length. Winget also doesn't show any source for MS Store apps with winget list.

Steps to reproduce

1. Open command prompt
2. Run winget search Whiteboard

Expected behavior

The MS Store apps have their MS Store IDs as the IDs in winget.

Actual behavior

Example:

G:\>winget search Whiteboard

Any other software?

Reproduce the report with winget search Whiteboard, then compare the corresponding winget list and winget export results for the msstore source. Trace the CLI handling for that source and verify that Store packages retain their Store IDs and appear in both commands.
