Can't construct QFont.Tag, preventing use of QFont.setFeature()

QFont::setFeature() was introduced in Qt 6.7 and it takes a QFont::Tag.

PySide6 6.8.2 does not allow constructing a QFont.Tag with a four-character code, which prevents using QFont.setFeature():

tag = QFont.Tag("tnum")  # <-- TypeError
font = QFont()
font.setFeature(tag, 1)

The following constructors (described in C++ docs) are also missing (AttributeError):

tag2 = QFont.Tag.fromString("tnum")
tag3 = QFont.Tag.fromValue(0x746e756d)
