Detection of different versions of Qt documentation when there is only one

This happens when, on example of OpenSUSE TW, Qt updates. New Qt version with new documentation makes records in ./config/QtProject/qtcreator/helpcollection.qhc (when QtCreator starts). And after each update of Qt in helpcollection.qhc make new records about new documentation versions that points to the same *.qch files in system /usr/share/doc/qt6. So removing helpcollection.qhc solves this issue. I guess this is a QtCreator's issue, because removing in settings dialog old documentation versions doesn't work, they appear again and again after restart of QtCreator.

It looks like - have a look at the attached screenshots.
