Like I stated here in your previous PR. These icons have already been updated on the develop branch, and thus don't need to be updated again. The icons will be available on the website and npm when we make our next release

Also worth noting that the branch should be based on develop instead of master, so you don't get all those extra bump and merge commits :)
