Use @gitlab/favicon-overlay instead of common_utils
What does this MR do?
As part of #287678 (closed), we've moved our favicon overlay utilities over to their own package (many thanks to @winniehell!). This package has significantly better test coverage than our current one and will also free up some CI resources since it's tests are decoupled from our pipeline.
