…ext-shadow, a=testonly

Automatic update from web-platform-testsCorrect serialization of box-shadow and text-shadow

Following w3c/csswg-drafts#2305, the canonical serialization for box-shadow was changed to the color then lengths. https://drafts.csswg.org/css-text-decor-3/#text-shadow-property also defines the canonical serialization for text-shadow as the color and then lengths. This caused the test to fail in Firefox, Chrome, and Safari. Update the test to match the spec in both instances.
