    Description

      This code gives a mypy error:

      """Bug"""
from PySide6.QtCore import QFileSystemWatcher

w = QFileSystemWatcher()
w.fileChanged.connect(None)
print("Done.")

      bug.py:5: error: "QFileSystemWatcher" has no attribute "fileChanged"
      Found 1 error in 1 file (checked 1 source file)

      I have found https://bugreports.qt.io/browse/PYSIDE-1318 and https://github.com/qtproject/pyside-pyside-setup/commit/f57efb8c0ff616e345807b2671705363dd0d6b39 but they seem unrelated to this issue - that bug reports missing properties for signals. In this issue, mypy reports missing signals.
