Draft: Add qmlformat ci template
This template makes sure that the QML code is consistently formatted. This uses the qt6 versions due to two main reasons. The qt6 version is way better than the qt5 version and this also helps with verifying statically that the qml files in a project are syntaxely compatible with qt6.
Can be seen in action in network/tokodon!41
