Fixes #12 Add missing ominauth require

[the-spectator]

Fixes #12

The mentioned issue happens when omniauth is not added explicitly to Gemfile, hence bundler does not require it.

But since omniauth-rails_csrf_protection assumes the ominauth is already required, it errors out when user only adds omniauth-rails_csrf_protection but does not add omniauth to Gemfile.

This PR adds missing require for omniauth gem.

Bug script:

require 'bundler/inline'

gemfile(true) do
  source "https://rubygems.org"

  git_source(:github) { |repo| "https://github.com/#{repo}.git" }

  gem "rails", '7.0.0.alpha2'
  gem 'omniauth-rails_csrf_protection'
end

class TestApp < Rails::Application
  config.root = __dir__
  config.eager_load = false
end

ENV["DATABASE_URL"] = "sqlite3::memory:"

Rails.application.initialize!
