[Bug] XAxis WithXAxisOpts show设置为false时候，line.JSON返回的数据里面没有show属性，设置为true的时候会带上

[lufeng4828]

Describe the issue

line := charts.NewLine()
	line.SetXAxis(names).AddSeries(metric, items).
		SetGlobalOptions(
			charts.WithTooltipOpts(opts.Tooltip{
				Show:    true,
				Trigger: "axis",
			}),
			charts.WithColorsOpts(opts.Colors{"#0052d9"}),
			charts.WithLegendOpts(opts.Legend{Show: false}),
			charts.WithXAxisOpts(opts.XAxis{
				Show: false,
			}),
		).
		SetSeriesOptions(
			charts.WithMarkPointNameTypeItemOpts(
				opts.MarkPointNameTypeItem{Name: "Maximum", Type: "max"},
				opts.MarkPointNameTypeItem{Name: "Average", Type: "average"},
				opts.MarkPointNameTypeItem{Name: "Minimum", Type: "min"},
			),
			charts.WithAreaStyleOpts(
				opts.AreaStyle{
					Opacity: 0.3,
					Color:   "#0052d9",
				},
			),
			charts.WithMarkPointStyleOpts(
				opts.MarkPointStyle{Label: &opts.Label{Show: true}}),
		)
line.Validate()
line.JSON()

需要把 type XAxis struct 里面的Show的json tag中的omitempty去掉
// Set this to false to prevent the axis from showing.
Show bool json:"show,omitempty"

How to reproduce this issue

charts.WithXAxisOpts(opts.XAxis{
Show: false,
}),

line.Validate()
line.JSON()

Hi @lufeng4828, 确实有bool类型不一致导致序列化后出来的问题。 建议升级到v2.4.0-rc1 试试。
