Create story for `custom-select` with multiple items selected

[andrewtpham]

Current behavior With the use of custom-select in the layer stepper, the data type is now shown. For single select the data type works fine but for multiple select such as the tooltip description there is an additional styling check mark displayed where the right-area-span is shown. We need to create a story and style the checkmark in a position that works with the right area span.

To Reproduce See example from Layer Stepper in Dots on the Tooltip description page:

Expected behavior

• Explore shifting the right span area to the left so that the check mark can display in its current position: Here's an example design:

@Kimaiyo077 could you help me have a look at how best to implement this based on whether an h-select is using the multiple option? For single select on the h-select we should keep the same styling as in right-data-span currently.

Here is the right amount of margin-right: 1.75rem;
