* Add new icon for mini cart block (inserter).
See https://github.com/woocommerce/woocommerce-blocks/issues/6617.
* Adjust size of SVG
The new SVG was rendering a little bit smaller than the original icon.
Potentially because of the mask and the artboard size.
This commit adjusts the size to render at the same size as the original
version of the icon in the inserter.
