FactoryBot introduces ActiveSupport monkey patching to Hashes

[jedschneider]

Description

We discovered that our runtime code in production had an expectation to be able to call symbolize_keys on a Ruby hash even though we had no dependency on activesupport. The tests flexed this code and passed. I was able to produce an example script that illustrates that factory_bot is injecting code into base classes which can mask production issues during test.

Reproduction Steps

begin
  {}.symbolize_keys
rescue NoMethodError => e
  puts "\e[31m------ WARNING ----- Hashes do not respond to symbolize_keys ---------\e[0m"
end

require 'bundler/inline'

gemfile(true) do
  source 'https://rubygems.org'
  group :development, :test do
    gem 'factory_bot'
  end
end

require 'factory_bot'

puts "FactoryBot Version: #{FactoryBot::VERSION}"

begin
  {}.symbolize_keys
  puts "\e[31m------ WARNING ----- Hashes now respond to symbolize_keys ---------"
  puts "This behavior is introduced by ActiveSupport\e[0m"
rescue NoMethodError => e
  puts " ------------ EXPECTED ---- Hashes still do not respond to symbolize_keys"
end

Expected behavior

FactoryBot should not change behavior of classes it does not own.

Actual behavior

the EXPECTED line prints in the above script.
