Wrong platform information for PopOS

[vladislav-sharapov]

Describe the bug

host.Info() doesn't return correct platform information in the case of a PopOS system.

To Reproduce

package main

import (
    "fmt"
    "github.com/shirou/gopsutil/v3/host"
)

func main() {
    hostInfo, _ := host.Info()

    fmt.Printf("Platform: %s\nPlatform family: %s\nPlatform version: %s\n", hostInfo.Platform, hostInfo.PlatformFamily, hostInfo.PlatformVersion)
}

Output:

Platform: debian
Platform family: debian
Platform version: bookworm/sid

Expected behavior

I expect more relevant information from /etc/os-release, for instance:

Platform: PopOS
Platform family: ubuntu
Platform version: 22.04

Environment (please complete the following information):

• Linux: [paste contents of /etc/os-release and the result of uname -a]
