### Brief description of your issue

When checking the Python.PythonInstallManager install options, the MSIX version lacks a scope declaration (is it machine, is it user?). I would assume it's meant to be user scope judging by MSIX.

### Steps to reproduce

This was based on an inspection in Robopack, but it can be seen there is no scope declaration in the source file.

### Actual behavior

Scope is empty.

### Expected behavior

A scope is expected.

### Environment

```raw
N/A
```

### Screenshots and Logs

https://github.com/microsoft/winget-pkgs/blob/master/manifests/p/Python/PythonInstallManager/26.0.240.0/Python.PythonInstallManager.installer.yaml (file for ref that the MSI has a scope, but the MSIX does not)

Open manifests/p/Python/PythonInstallManager/26.0.240.0/Python.PythonInstallManager.installer.yaml and compare the MSIX installer entry with the MSI entry that declares a scope. Add the missing MSIX scope using the intended value, then confirm the manifest shows a non-empty scope for both installer types.
