Bug Report: Invalid module name

[ydakuka]

Actual behavior

I run the command:

$ rubocop-extension-generator rubocop-foobar

And I got the following files:

# rubocop-foobar/sig/rubocop/foobar.rbs

module Rubocop
  module Foobar
    VERSION: String
    # See the writing guide of rbs: https://github.com/ruby/rbs#guides
  end
end

# rubocop-foobar/spec/rubocop/foobar_spec.rb

module Rubocop
  module Foobar
    VERSION: String
    # See the writing guide of rbs: https://github.com/ruby/rbs#guides
  end
end

Then I run rspec:

ydakuka@yauhenid:~/Work/rubocop-foobar$ rspec spec/

An error occurred while loading ./spec/rubocop/foobar_spec.rb.
Failure/Error:
  RSpec.describe Rubocop::Foobar do
    it "has a version number" do
      expect(Rubocop::Foobar::VERSION).not_to be nil
    end
  
    it "does something useful" do
      expect(false).to eq(true)
    end
  end

NameError:
  uninitialized constant Rubocop
  Did you mean?  RuboCop
# ./spec/rubocop/foobar_spec.rb:3:in `<top (required)>'
No examples found.

Expected behavior
