We had an @images-path variable in LessCSS that was used to link to

the Ink images, but this had a couple of problems. One is that the name

was too generic and likely to conflict with consuming packages. The

other is that it pointed to "ink", which wasn't likely to resolve well

in practice anywhere.
We now have an @ink-path variable that points to @beanbag/ink, and w

use that to build paths as necessary.
This means no images-specific variable, so the references now compensate

by including the images directory in the referenced path.

Tested the images in Storybook, making sure they loaded.
Successfully built packages.
