Qt 6.7.1 for Debian Trixie

I am not familiar with this prozess but I would like to mention that it would be important to update the debian packes from 6.4.2 in Bookworm to 6.7.1 in Trixie. https://packages.debian.org/search?searchon=sourcenames&keywords=qt6-base

In our project it is relatively simple to keep compatibility to Qt 6.5 but especially for some new QML mechanisms it looks impossible with reasonable effort to keep compatibility with Qt 6.4.2.

QTBUG-108684 is an example. We started to use qml lint and want to moderinze our code. But using `pragma ComponentBehavior: Bound` in combination with a Loader is impossible because of that bug still contained in Qt 6.4.2. So we are not able change this lint category from info to warning.
