🐜 fix(scripts): Use class codes to check for lspci GPU devices (#168)

Fixes gpu_helpers returning "Non-VGA" devices as GPUs.

I was curious about DeepSeek's so I tried it's hand with this as my head
isn't quite up-to-speed yet 😅
But yeah it seems less error-prone than previous naive string-approach.
