Missing documentation for QFlags' equality operators

QFlags has equality and inequality operators in the source code which are documented, but whose documentation is not generated.

https://doc.qt.io/qt-6/qflags.html

qflags.qdoc has documentation, for instance:

/*!
    \fn template <typename Enum> bool operator==(QFlags<Enum> lhs, QFlags<Enum> rhs)

but for whatever reason it's not generated. Maybe because these operators are hidden friends?
