Update icon for sorting component

[kasya]

Is your feature request related to a problem? Please describe.
The icons that we currently have on a SortBy component is a bit misleading. When the order set to Descending it means that we go from largest to smallest item, going down. Opposite for ascending order where we should go up from smallest to largest item.
Currently the icons are misleading in the direction of sorting, where descending shows arrow pointing up and ascending shows arrow pointing down.

Describe the solution you'd like
I think we should find a more appropriate icon that would show the direction of order more clear (down or up).
I checked FA icons and it seems that the fix could be as simple as changing the icons to these for Descending and for Ascending order.
