Fedora 32 No system ruby at all. No rvm on my system at all.

Steps to reproduce:

From scratch:

248208  2020-09-27 16:16:14 - git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.8.0
248209  2020-09-27 16:16:21 - cd .asdf
248215  2020-09-27 16:18:14 - asdf plugin-add ruby
248219  2020-09-27 16:19:11 - asdf list-all ruby
248223  2020-09-27 16:21:40 - asdf install ruby 2.7.1
248224  2020-09-27 16:24:19 - asdf global ruby 2.7.1

Strange. No idea what is going on. asdf-ruby doesn't do anything with rvm either.

OK, I found out what was going on ( thanks !! to shoshin on freenode#ruby )

I deleted everything RVM from the machine, EXCEPT all the crap rvm had put in the shell as functions and env vars!!!

Maybe add to the README or somewhere :

### Migrating from RVM:
Make certain that you remove ALL of rvm.  It is tenacious.
* `rm -rf .rvm`
* Check all these files for remnants of `rvm`

grep -i rvm .bashrc .bashrc.local .bash_profile .profile .mkshrc .zlogin .zshrc

* **_NOW REBOOT_** to get all the functions and env vars that have rvm in them out of your environment
  * `( set | env ) | grep -i rvm` will show invasive it is

@wwalker can you take a look at https://github.com/asdf-vm/asdf-ruby/pull/306?

@Stratus3D thank you, I made my comments there. It looks good and is well worded.
