Support for Command Substitution

[mullermp]

Is your feature request related to a problem? Please describe.
I use multiple ruby versions for each of my projects. I manage these versions with chruby. The path to Rubocop for these versions is different. i.e

~/.gem/ruby/3.0.2/bin/rubocop
~/.gem/ruby/2.7.4/bin/rubocop

I want to be able to use rubocop for whatever ruby version is in my project.

Describe the solution you'd like
I want to set my command to $(which rubocop) and have it use the result as the absolute path.

Describe alternatives you've considered
Is there a way to have project level configuration?

Maybe chruby-exec can support .ruby-version but that doesn't seem likely since the feature request is 7 years old. Issue: postmodern/chruby#211

#411 but it's on WIP, I stopped the development because I am currently using VSCode, I am not using Atom anymore, sorry.
