Add ResizeObserver message to ignoreErrors option

[srallen]

Please request review from @zooniverse/frontend team. If PR is related to design, please request review from @beckyrother in addition.

Package: app-projects, app-content-pages

I've set Sentry to ignore the ResizeObserver error message. This is benign according to the spec authors and there's an open issue to change it to be a warning. See: WICG/resize-observer#38
