Issue in /src/pages/guides/creating-python-plugin.md

I was going over the "Creating a Python plugin" tutorial, and had issues running the custom_import.py plugin code. It seems that PySide 2 is not supported in the most recent version of Substance Painter.

Is the following more appropriate? While I still had errors after making this change, at least it loaded the plugin.

from PySide6 import QtWidgets
from PySide6.QtGui import QAction

Comece por src/pages/guides/creating-python-plugin.md e revise o exemplo custom_import.py junto com os imports de PySide2 e PySide6 relatados. Confirme qual forma de import é compatível com a versão atual do Substance Painter e, em seguida, atualize o tutorial para que o exemplo seja carregado sem o problema de import relatado.
