Added support to macOS 15 Sequoia

[AngeloAvv]

Hey! I added Sonoma scripts and updated existing ones to keep this project working with the latest macOS 15 Sequoia.

I also installed macOS 15 Sequoia into my Proxmox instance using your OpenCore v20 files and following the guide for macOS 13 Ventura.

Thank you so much for your work!
