port to Qt6
Important note when we merge the code: https://mail.kde.org/pipermail/kde-devel/2023-September/002036.html Warn the i18n team: send a merge request to sysadmin/repo-metadata mentioning the localization team, and after getting a proper review, please wait for us (translation) to merge it and move the translations at the right time.
