At some point moved from hljs pure source to their CDN assets, but we did not change the way we created the HLJS bundle. The CDN asset comes with their "common" languages already included, so we were duplicating around 35 languagues in the bundle we create. This patch includes a list of their current common langs so we never double bundle those. Changes in size are significant. Numbers before minimization/compression are 747.53 KB before and 117.57 KB after.
