CircleCI 403 Forbidden in HTML artifacts

Hiya @Eric89GXL - it looks like this is directly due to our recent change with redirecting artifacts: https://circleci.com/changelog/#artifacts-redirects. We recently rolled out a change that allowed JSON files through CORS, but it looks like there are some other file types we should consider allowing through. I’ll pass this along internally, and cross-post this to the GitHub discussion for visibility
