Fix Microsoft Store publish package input

[Xueyang-Song]

Summary

• publish the built .msixupload directly with msstore publish instead of passing the WinUI project folder
• avoid the Store CLI UWP/WinUI project detection path that tries to restore packages during publish
• update Store workflow docs to match the supported Store CLI command shape

Validation

• inspected the failing Store workflow logs for run 25479557114/job 74760460192
• inspected Microsoft Store CLI source and confirmed direct .msixupload input uses the MSIX publisher path
• git diff --check
• parsed .github/workflows/jithub-store-release.yml with PyYAML
