Is steps.ruby.outputs.ruby-path necessary?

[eregon]

The README shows:

    - name: Print version
      run: ${{ steps.ruby.outputs.ruby-path }} --version

Is there a reason to use ${{ steps.ruby.outputs.ruby-path }} --version instead of just ruby --version?

It seems the installed Ruby's bin directory is added to PATH:

ruby-build-action/src/index.js

Line 46 in d297155

core.addPath(`${process.env.HOME}/local/rubies/${rubyVersion}/bin`)

And that should be enough, just like setup-ruby and every other CI.
So I would suggest to simplify in the README, and not need an output variable as that's quite verbose.

Thanks @eregon, that's good input. I'll change that!
