QKeySequence.StandardKey is not accepted where a QKeySequence is valid

[AWhetter]

Consider the following code example:

import sys
from PySide2 import QtCore, QtGui, QtWidgets

class Window(QtWidgets.QWidget):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self._label = QtWidgets.QLabel("Try Delete", self)
        self._shortcut = QtWidgets.QShortcut(QtGui.QKeySequence.StandardKey.Delete, self)
        self._shortcut.activated.connect(self.on_delete)

        self._layout = QtWidgets.QHBoxLayout()
        self._layout.addWidget(self._label)

        self.setLayout(self._layout)
        self.resize(150, 100)
        self.show()

    @QtCore.Slot()
    def on_delete(self):
        print("Deleting!")

app = QtWidgets.QApplication(sys.argv)
win = Window()
win.show()
sys.exit(app.exec_())

This code successfully runs with PySide2, and opens a window where if you press "Delete" then a message is output to the terminal.
mypy raises errors with this code, however:

file.py:9: error: No overload variant of "QShortcut" matches argument types "StandardKey", "Window"  [call-overload]

PySide2 incorrectly typed the places where is accepts a QKeySequence as QKeySequence | str, when it actually accepts Union[PySide6.QtGui.QKeySequence, PySide6.QtCore.QKeyCombination, PySide6.QtGui.QKeySequence.StandardKey, str, int]. This was corrected in PySide6.

I believe that types-PySide2 can also be updated to accept Union[QKeySequence, QKeySequence.StandardKey, str, int] where QKeySequence | str is currently accepted.
