Enable Performance/UnfreezeString cop
In Ruby 2.3 or later, `String#+@` is available and `+@` is faster than `dup`.
```ruby
# frozen_string_literal: true
require "bundler/inline"
gemfile(true) do
source "https://rubygems.org"
gem "benchmark-ips"
end
Benchmark.ips do |x|
x.report('+@') { +"" }
x.report('dup') { "".dup }
x.compare!
end
```
```
$ ruby -v benchmark.rb
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
