qdoc generates multiple qhash-proxy.html files

Various qHash() overloads generate API documentation with the same file: qhash-proxy.html:

find . -name qhash-proxy.html
./qtcore5compat/qhash-proxy.html
./qtmqtt/qhash-proxy.html
./qtnetwork/qhash-proxy.html
./qtpositioning/qhash-proxy.html

Because they share the same file name (though being generated in different directories), only one of them is available on the webserver: doc.qt.io/qt-6/qhash-proxy.html
