Subject: [PATCH] [Cmake] Update FindPySide2Tools for PySide2 5.14 - issue
 #4229

Since PySide2 5.14, 'pyside2-rcc' and 'pyside2-uic' have been renamed into plain 'rcc' and 'uic'.
This leads FindPySide2Tools.cmake to no longer find rcc/uic, as reported in bug #4229 (https://www.freecadweb.org/tracker/view.php?id=4229) and prevents compilation.
FindPySide2Tools has been updated accordingly.
