this change should be automatic.

**MockWebServer has a new coordinate and package name.** We didn’t like that our old artifact
depends on JUnit 4 so the new one doesn’t. It also has a better API built on immutable values. (We
intend to continue publishing the old `okhttp3.mockwebserver` artifact so there’s no urgency to
migrate.)
