[FEATURE] Qt6 AppImage

[pbek]

It would be great to have a Qt6 AppImage (instead of Qt5). Not everything seems to work, tho...

• [x] Build process working
• [x] AI Settings layout fixed (#3075)
• [ ] Script engine working
• [ ] Incompatible version of OpenSSL (#3174)

Warning: script errors: QList(file:///home/omega/Code/qownnotes-scripts/list-maker/list-maker.qml: module "QtQml.WorkerScript" is not installed, file:///home/omega/Code/qownnotes-scripts/list-maker/list-maker.qml: module "QtQml.Models" is not installed, file:///home/omega/Code/qownnotes-scripts/list-maker/list-maker.qml: module "QtQml.WorkerScript" is not installed, file:///home/omega/Code/qownnotes-scripts/list-maker/list-maker.qml: module "QtQml.Models" is not installed) ((null):0, (null))

Even tho the libs needed for scripting, like usr/lib/libQt6Qml.so.6, usr/lib/libQt6QmlModels.so.6 and usr/lib/libQt6QmlWorkerScript.so.6 are present, scripts are not working. 🤔
