Implement prompt section for ruby version

[matchai]

Feature Description

This feature is implemented once we have reached feature parity with the following spaceship section: https://github.com/denysdovhan/spaceship-prompt/blob/master/sections/ruby.zsh

Expected Behaviour

• Reach feature and configuration parity with the implementation in spaceship-prompt
• Show ruby version using the following version managers:
  • [x] rvm
  • [x] rbenv
  • [x] chruby
  • [x] asdf

Are there any other ruby version managers that we should create for this feature to be complete? Assuming asdf is a placeholder 😄

@kyleholzinger The ruby version managers left are chruby and asdf (the unchecked boxes above).

asdf is indeed real 😆: https://github.com/asdf-vm/asdf

Hahahah oh man, alright well I'm not familiar with that one but I'll give a shot at chruby!

[avegancafe]

Were we still thinking of doing asdf? @matchai #46 only did chruby, not sure if that's in the works

[tiffafoo]

Yeah asdf still open @kyleholzinger. It just closed because when you have an issue preempted by closes/fix, etc. it closes the issue automatically. Reopened!
