Incorrect stub for QtGui.QImage.loadFromData

[AWhetter]

Currently QtGui.QImage.loadFromData is typed as follows:

def loadFromData(self, data: PySide2.QtCore.QByteArray | bytes, aformat: bytes | None = ...) -> bool: ...

PySide2 documents this function with the equivalent of this:

@typing.overloads
def loadFromData(self, fileName: str, format: str | None = ...) -> bool: ...
@typing.overloads
def loadFromData(self, data: PySide2.QtCore.QByteArray | bytes, aformat: str | None = ...) -> bool: ...

Using the below code example:

from PySide2 import QtCore, QtGui

image = QtGui.QImage()
with open("/path/to/image.png", "rb") as in_f:
    image.loadFromData(QtCore.QByteArray.fromBase64(in_f.read()), "PNG")

I get the following error when running mypy:

tst.py:5: error: Argument 2 to "loadFromData" of "QImage" has incompatible type "str"; expected "bytes | None"  [arg-type]
