Remove Qt DLLs from PySide6 and suppress errors

Add -ErrorAction SilentlyContinue to Get-ChildItem calls and add a check for a lib\PySide6 folder to remove matching Qt DLLs there as well. This prevents failures when no files match the patterns and ensures duplicate Qt DLLs packaged under PySide6 are cleaned up. Applied to both DLL-cleanup sections of the Windows build workflow.
