Fix docker support (#258)

Docker image was failing to build. Base image and some dependency versions needed to be pinned. * Rollback base Alpine linux image to v3.11. * Explicitly install Rails v5.2.6. * Copy Gemfile and warclight.gemspec files to working directory before installing Rails and warclight.
