Fix AMD GPU firmware installation by adding non-free-firmware repository

- Add non-free-firmware repository for Debian before attempting to install firmware-amd-graphics
- Support both Debian Bookworm (12) and Trixie (13)/Sid
- Install firmware-amd-graphics for all AMD GPUs detected, not just APUs
- Improve error handling with warning message if firmware installation fails

Fixes #10177
