Ability to export csv from PIM with SKUs linked to assets

Use case: Customer (Ryan from Moso Bamboo) asked for functionality of exporting a CSV file with selected products and variants that includes assets (in form of public link) linked to them. This helps them send their product information list, to different vendors like HomeDepot to be sold through them.

Note that this work is blocked and can be implemented only when product variants and assets are visible on the PIM table.
