mem.VirtualMemory() returns zero swap stats on MacOS 12.1 Monterey

[rustomax]

Swap stats are at zero while sysctl -n vm.swapusage returns non-zero values on Monterey

To Reproduce

package main

import (
	"fmt"
	"github.com/shirou/gopsutil/mem"
)

func main() {
	vmStat, _ := mem.VirtualMemory()
	fmt.Printf("%v\n", vmStat)
}

Output:

{"total":68719476736,"available":54567813120,"used":14151663616,"usedPercent":20.59338092803955,"free":49884401664,"active":6553595904,"inactive":4683411456,"wired":4498362368,"laundry":0,"buffers":0,"cached":0,"writeback":0,"dirty":0,"writebacktmp":0,"shared":0,"slab":0,"sreclaimable":0,"sunreclaim":0,"pagetables":0,"swapcached":0,"commitlimit":0,"committedas":0,"hightotal":0,"highfree":0,"lowtotal":0,"lowfree":0,"swaptotal":0,"swapfree":0,"mapped":0,"vmalloctotal":0,"vmallocused":0,"vmallocchunk":0,"hugepagestotal":0,"hugepagesfree":0,"hugepagesize":0}

Expected behavior:
Match values returned by sysctl

sysctl -n vm.swapusage
total = 2048.00M  used = 676.25M  free = 1371.75M  (encrypted)
