Ruby 2.3.3 / 2.4.0

[hwhelchel]

Could you please add ruby 2.3.3 and 2.4.0 to the build image? Thanks!

The best way to get support for a particular version of ruby is to add a .ruby_version to your repo. We will then install (and cache) that one reliably.

I misspoke! We only support a few versions. We will revisit this when we look at updating the build script to actually do what I claimed it does.
