Upgrade to Java Docker client 3.2.12

Version 3.2.12 of the Docker client improves Windows compatibility by defaulting to named pipes rather than UNIX-domain sockets to talk to the Docker daemon on Windows. Previously, users had to explicitly set `DOCKER_HOST` on Windows.

Fixes revolut-engineering#15
