Update gpus.json

[88plug]

Correct rtx4060ti memory

Appears there is conflicting intel on the amount of RAM on part number 2803 as some references show 8GB of RAM - which is current spec in gpu.json. But will use provided nvidia-smi provided as source of truth and based on this can be merged.

Thanks @chainzero

FYI:
The vendor ID (e.g., 10de for NVIDIA) and product ID (e.g., 2803 in this case) can be accompanied by a unique subsystem ID, which distinguishes the specific VRAM characteristics (such as size) of the GPU.

For example, according to this reference, a 10de:2803 GPU with a subsystem ID of 16E3 corresponds to a model with 8 GB of VRAM. In contrast, 88plug's 10de:2803 GPU features a different subsystem ID, indicating distinct VRAM specifications.

Unfortunately, Akash does not support the subsystem ID's yet.

I've opened an issue to address this akash-network/support#256
