[Sku selector] - Fix sku slider rendering the parent shelf

[agnaldopsfilho]

What problem is this solving?

The "displayMode": "slider" prop of the sku-selector component does not behave correctly when used inside a shelf with slider, duplicating the same shelf inside the sku selector component.
This problem is caused because the slider component uses the list-context to display the slides, and being inside another slider generates context conflicts.
To resolve this I imported the ListContextProvider and placed the SliderLayout inside it passing the prop list={[]} to the provider in the Variation component of SKUSelector.

How to test it?

1. Go to Workspace
2. Look at the first shelf in home:
   

Screenshots or example usage:

• Before (the shelf is rendered inside the sku selector component on click on the slider's arrows) :
  

• After (the slide behaves correctly):
  

Example usage:

 "product-summary-sku-selector#shelf": {
    "props": {
      "displayMode": "slider",
      "sliderItemsPerPage": {
        "desktop": 2,
        "tablet": 2,
        "phone": 2
      },
      "sliderDisplayThreshold": 1,
      "showVariationsLabels": "none"
    }
  }
