COMP: Update ctkPythonConsoleTest1 to use operator| for Qt 6 compatibility

This fixes the following warning:

```
/path/to/CTK/Libs/Scripting/Python/Widgets/Testing/Cpp/ctkPythonConsoleTest1.cpp: In function ‘int ctkPythonConsoleTest1(int, char**)’:
/path/to/CTK/Libs/Scripting/Python/Widgets/Testing/Cpp/ctkPythonConsoleTest1.cpp:47:49: warning: ‘constexpr QKeyCombination Qt::operator+(Qt::Modifier, Qt::Key)’ is deprecated: Use operator| instead [-Wdeprecated-declarations]
   47 |   otherShortcuts << QKeySequence(Qt::CTRL + Qt::Key_Space);
      |                                                 ^~~~~~~~~
```
