Don't include `images/toolbarButton-editorInk.svg` in the `gulp components` build (issue 15260)

Given that this image is intended specifically for the default viewer, we simply use the CSS preprocessor to remove the image reference in the `gulp components` build.
Considering that the issue only affects a CSS file, I don't believe that replacing the *just released* PDF.js version is actually necessary here.
