Qt 6.8.0: 3rd party component update: Qt OpcUA

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

Check if we need to update 3rd party modules in Qt OpcUA
Check if documentation of 3rd party component usage is correct and do needed updates. Documentation here: https://doc-snapshots.qt.io/qt6/licenses-used-in-qt.html
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.
