legacy version check doesn't support "ruby-2.5.0" format

[gouthamvel]

I'm working on open source projects and they use .ruby-version file with format a bit different from asdf legacy version.

  $ cat .ruby-version
  ruby-2.5.0

  $ ruby -v
  ruby ruby-2.5.0 not installed

it works if I change the content to 2.5.0.

We will need to update the asdf-ruby code to parse this version format as well. Thanks for reporting this!

Just wanted to say I ran into the same issue here and stumped me for a little bit. This was for a new Rails 5.2.1 project (so its likely to be a very common issue) as the .ruby-version comes pre-baked like this.

This does not work for me. Even with the latest asdf and asdf-ruby git repo checked out on zsh.

asdf: commit aa5f7f16800d773d2d1b6c76f323d2047d0db404 (HEAD, tag: v0.6.0)
asdf-ruby: commit b94f282 (HEAD -> master, origin/master, origin/HEAD)

.ruby-version generated by rails with content: ruby-2.5.3:

✗ asdf list ruby    
  2.5.3
✗ cat .ruby-version 
ruby-2.5.3%              
✗ ruby -v
ruby ruby-2.5.3 not installed

I suspect bin/get-version-from-legacy-file is not called at all. I can return or even delete the file without a notable difference.
