Incorrect help.png path in help.sccs

Problem/Motivation

Help.png icon path is not correct and icon is not found when checking site.

Steps to reproduce

When installed in Drupal, bootstrap_barrio is installed in /themes/bootstrap_barrio. The expanded file path for the help.png icon in help.css is /themes/contrib/bootstrap/images/help.png. By observation this is wrong. Also when running a link checker I get an error when it tries to retrieve help.png.

Proposed resolution

Either change the line
background-image: url(/themes/contrib/bootstrap/images/help.png);
to
background-image: url(/themes/contrib/bootstrap_barrio/images/help.png);
or to the code that is used in icons.sccs
background-image: url(/#{$barrio_path_images}help.png);
