Bar chart, x-axis or zero axis is overlapping the bars.

## What did you expect to happen?

I want to draw the x-axis line on top of the bars. (Check the image)

## What happened instead?

It's currently drawn underneath the bars causing the overlapping issue. (Check the image)

## What did you do?

## DGCharts Environment

**DGCharts version/Branch/Commit Number:**
**Xcode version: 15.2
**Swift version: 5.2
**Platform(s) running DGCharts: 5.1.0
**macOS version running Xcode:**

Start by reproducing the bar chart using the reported xAxisSetup, leftAxisSetup, and rightAxisSetup configuration and inspect DGCharts' axis and bar rendering order. Confirm how the x-axis or zero line is drawn relative to bars. Done means the configured x-axis and zero axis render on top of the bars without breaking other axis or bar-chart behavior.
