Subject: [PATCH] fix: Fix DRM workaround for Tizen and Xbox with ac-3 boxes
 (#3631)

content_workarounds.js was introduced for Tizen and Xbox platforms. We found that that meant a regression where certain streams were unable to be played.

This PR adds ac-3 into the content workarounds in the same was as ec-3 to ensure these streams can be played once more.

Issue #3589
