function views_timelinejs_library_info_alter in Views TimelineJS integration 8.3

Implements hook_library_info_alter().

Provides backward compatibility for sites that originally installed version 8.x-3.0 which gave the TimelineJS CSS libraries a weight of "theme."

@todo Remove this in the next major version.
