added gpu driver query for windows

[hingino]

Description

GPU does not currently return driver version for Windows. Adding these 3 lines reliably returns driver version

Test

package main

import (
	"fmt"

	"github.com/jaypipes/ghw"
)

type gpuInfo struct {
	Vendor        string
	Name          string
	OfflineDriver string
}

func GetGpuData() []gpuInfo {
	gpus := []gpuInfo{}

	cards, err := ghw.GPU()
	if err != nil {
		fmt.Printf("Error getting GPU info: %v", err)
	}

	for _, card := range cards.GraphicsCards {
		gpu := gpuInfo{
			Name:          card.DeviceInfo.Product.Name,
			Vendor:        card.DeviceInfo.Vendor.Name,
			OfflineDriver: card.DeviceInfo.Driver,
		}

		gpus = append(gpus, gpu)
	}

	return gpus
}

func main() {
	gpus := GetGpuData()

	for _, gpu := range gpus {
		println("GPU Vendor: ", gpu.Vendor)
		println("GPU Name: ", gpu.Name)
		println("Driver: ", gpu.OfflineDriver)
	}
}

Returns before update

GPU Vendor:  NVIDIA
GPU Name:  NVIDIA GeForce RTX 3060 Ti
Driver:

Return after update

GPU Vendor:  NVIDIA
GPU Name:  NVIDIA GeForce RTX 3060 Ti
Driver:  31.0.15.3118
