Commit Message

Improve build_validation_options method

Use `<<` instead of string interpolation

```ruby
require 'benchmark/ips'

def interpolation(options)
  name = 'name'
  name = "#{name}#{options[:multiple] ? '[]' : nil}"
end

def push(options)
  name = 'name'
  name << '[]' if options[:multiple]
end

Benchmark.ips do |x|
  x.report('interpolation (true)')  { interpolation(multiple: true) }
  x.report('interpolation (false)')  { interpolation(multiple: false) }
  x.report('push (true)') { push(multiple: true) }
  x.report('push (false)') { push(multiple: false) }
  x.compare!
end
```

Result:

```
$ ruby bench.rb 
Warming up --------------------------------------

Calculating -------------------------------------
interpolation (true)      1.231M (± 5.1%) i/s -      6.161M in   5.017881s
interpolation (false)
                          1.144M (± 5.0%) i/s -      5.727M in   5.018903s

Comparison:
        push (false):  1528576.6 i/s
         push (true):  1402083.9 i/s - same-ish: difference falls within error

interpolation (false):  1144093.1 i/s - 1.34x  slower
