Martin von Zweigbergk d8feed9be4 copyright: change from "Google LLC" to "The Jujutsu Authors"
Let's acknowledge everyone's contributions by replacing "Google LLC"
in the copyright header by "The Jujutsu Authors". If I understand
correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any
concerns).
