Add Layout 2020 reftests regression report
This shows WPT reftests that fail in Servo with Layout 2020 but pass with Layout 2013, together with screenshots of the corresponding runs and HTML source code for the test and its reference. https://community-tc.services.mozilla.com/api/index/v1/task/project.servo.layout-2020-regressions-report/artifacts/public/regressions.html redirects to the latest report for the `master` branch.
