Fixes mismatch between expected gem version and installed gem version. As of now installed version of gem in prod is `3.0.3`, when we expect it to be 2.6.10. In Dockerfile in we were copying `/usr/local/bin/gem`, which is just a loader and doesn't decide rubygems version. Copying `/usr/local/lib/ruby/2.6.0/rubygem` from builder would most likely work but this seems unconventional and doesn't really save as much build time.
