Bullet is not centered in the heatmap legend

[felipefialho]

Description

When using type="heatmap" in the chart, the legend bullet appears slightly misaligned — it's not vertically centered. This seems to be due to an unnecessary top: 2px style, which is applied [here in the code](https://github.com/apexcharts/apexcharts.js/blob/05fa8e54b9ab9123619bb312f8159a2009d30f36/src/modules/legend/Legend.js#L90).

Steps to Reproduce

1. Create a chart with type="heatmap".
2. Observe the legend bullet.

Expected Behavior

The bullet should be vertically centered within the legend item.

Actual Behavior

The bullet appears slightly offset due to the top: 2px adjustment.

Never mind, this is visible on all existing samples. Thanks for reporting it.

@brianlagunas Can you point out where do you see this? I am unable to verify the issue on my end. @felipefialho It would be better if you can provide a codepen
