We don't ship rake with Portable Ruby as we've never actually needed it. Adding a Gemfile with gem "rake" paired with bundler-cache: true in the setup-ruby action might be the easiest solution but other alternatives are possible such as direct gem install rake steps.

@Bo98 I had the same thought, and pushed here. Will let @MikeMcQuaid make the final call though.

Would be nice to ship with it now I think. We were already using it in a few places and just added another.

I've bundled rake with Portable Ruby and reran with the new bottles.
