Qt 6.8.0: 3rd party component update: Qt Positioning

There was related discussion in Qt Contributors Summit. Memo: https://wiki.qt.io/QtCS2018_Third-Party_Sources_Policy_and_Security

1. Check if we need to update 3rd party components used (with security fixes if available)
2. Check if documentation of 3rd party component usage is correct and do needed updates. Documentation here: http://doc.qt.io/qt-6/licenses-used-in-qt.html
3. In case of 3rd party component update we need to document the update here: http://code.qt.io/cgit/qt/qtdoc.git/tree/doc/src/legal/licensechanges.qdoc

If there are questions, please contact dedicated R&D owner.
