pyside6-project does not handle .pyw files causing QT Creator to not launch the main.pyw

around line 40:-
in venv/lib/python3.11/site-packages/PySide6/scripts/project/project_data.py:-

                    if file.suffix == ".qml":
                        self._qml_files.append(file)
                    elif file.suffix == ".py":
                        if file.name == "main.py":
                            self.main_file = file
                        self._python_files.append(file)

This prevents QT Creator from setting main.pyw as the main project file to execute at the build stage. Qt Creator, under some circumstances (disable the pyside6 project tool, have a main.py file entry in the .pyproject file), successfully launch the desired main.pyw file. If there is no main.py entry in the .pyproject file - The build task will fail, and nothing will launch.

The QT Creator Is built from source with a fix suggested by QT to permit the execution of a main.pyw:-

[It looks like we have overseen the text/x-python-gui mime type when looking for executable python scripts in a project: fix is up at https://codereview.qt-project.org/c/qt-creator/qt-creator/+/504708]

I strongly suspect that a version of QT Creator with this fix has NOT been released.
