Change qt5-remoteobjects to qt6-remoteobjects

[Rovel]

I was trying to use omarchy-iso to build a custom image and was failing due to q5-remoteobjects not found, searching found that qt5-remoteobjects was removed so I upgraded to qt6, not sure if needs more editing but the ISO was built successfully.

It looks like the qt5-remoteobjects package was removed from the list in commit fceb710 on the dev branch (#3295).

Is qt6-remoteobjects needed?

Commenting it out broke build, but qt6-remote worked and I flashed a new device with that usb and it works, reading #1923 and lookig at kvantum arch repo: https://archlinux.org/packages/extra/x86_64/kvantum/ looks like its already in qt6 so I see no problem in the change

The dev branch seems to be building just fine. I'm honestly not sure what it is/was needed for in the first place. No point in keeping something that isn't needed.

This has already been removed from dev. Whatever needed it must have been removed a while ago.
