Fix an undefined variable error in Validator::Type

[yuta1024]

Description

validate method of Validator::Type has an undefined variable error.
I didn't touch the test code. Because current tests are already passed before fixing and after fixing too.
I wrote the following verification code and ran. After fixing, ChefAPI::Error::InvalidResource is raised correctly.

require 'chef-api'

group = ChefAPI::Resource::Group.new({groupname: 'test', actors: {}})
p group.validate!

Before fixing:

% bundle exec ruby test.rb
Traceback (most recent call last):

After fixing:

Local test is passing, but CI tests are failed. Those causes are older ruby version and lint existing code (this is not related my change).
What should I do?

Thanks @yuta1024. I'll cleanup the CI too
