QAbstractTextDocumentLayout::PaintContext selections field is not accessible to python

QAbstractTextDocumentLayout::PaintContext.selections is missing from the python bindings, in both PySide2 and PySide6. This leaves python code unable to highlight text when drawing a QTextDocument.

To reproduce, run this program:

#!/usr/bin/env python3
from PySide6.QtGui import QAbstractTextDocumentLayout
context = QAbstractTextDocumentLayout.PaintContext()
print(context.selections)

Expected result:

[]

Actual result:

Traceback (most recent call last):
  File "test_paintcontext_selections", line 4, in <module>
    print(context.selections)
AttributeError: 'PySide2.QtGui.QAbstractTextDocumentLayout.PaintCon' object has no attribute 'selections'

Workaround: Use PyQt instead of the official bindings. PyQt correctly exposes the selections attribute.
