Ultramarine 43 recommends Plasma, updates Raspberry Pi and adds Readymade preview

Ultramarine 43 retires the Flagship Budgie label, though Budgie remains available, and introduces KDE Plasma 6.5, as the new recommended Desktop Environment, with improved application permission management. A public preview of the Readymade installer is now available for full disk installs, and updated images enhance Raspberry Pi 4 support while adding Pinebook Pro compatibility.
