qdoc: Fix parsing of private signals

Parameters with a type QPrivateSignal were already removed when
constructing a FunctionNode from header declaration. This was
erraneously subtracted from the number of stored parameters when
parsing an \fn command.

Fixes: QTBUG-87731
Change-Id: I01409c0fcdab0dfbf8a0b9d22cded99618bdcc2d
