How would I go about making something like `rbenv-chef-workstation` happen?

https://github.com/docwhat/rbenv-chef-workstation

I use the heck out of this with rbenv, so that my intellij and such pick up the chef-workstation ruby. I am completely new to ASDF, so I'm not really even sure where to start. I didn't find anything with the google that helped me along this path, so I thought I'd ask here.

Do I need to make a PR to asdf-ruby to make it specially support the chef-workstation? Should there also be a chef-workstation plugin to manage versions of chef-workstation? Generally, it's installed as a package, and uses `/opt/chef-workstation` so it's mostly just a path definition, and how to get the shims.

Thanks!
