Describe the bug
In PartitionsWithContext(), the value ofPartitionStat.Opts doesn't use , when splition. So the options are in one string. As contrast, mount options are split when using /proc/1/mountinfo.

To Reproduce

package main

import (
	"fmt"

	"github.com/shirou/gopsutil/v4/disk"
)

func main() {
	partitions, err := disk.Partitions(true)
	if err != nil {
		log.Fatalln(err)
	}
	for _, each := range partitions {
		fmt.Printf("+%v\n", each)
	}
}

Expected behavior
Mount options of each mountpoint should be split by ,.
