Helpful things

Fixes

Could not tag a docker image as the latest using docker:publish/docker:publishLocal due to old sbt-native-packager version. This a backport of #6924 on master.

Purpose

Updates sbt-native-packager to the latest stable version.

Background Context

I tried to use dockerUpdateLatest in Docker := true, but it was broken in the sbt-native-packager used in Play 2.5.12
