Support usage alongside dry-auto_inject

[timriley]

Something like this should work:

require "dry-monads"
require "dry-auto_inject"

RSpec.describe "Using dry-auto_inject" do
  let(:transaction) {
    Class.new do
      include Dry::Transaction(container: Test::Container)
      include Test::Inject[:extract_email]

      step :symbolize

      def call(input)
        super(input).bind(extract_email)
      end
    end.new
  }

  before do
    module Test
      Container = {
        symbolize: -> input { Dry::Monads::Right(name: input["name"], email: input["email"]) },
        extract_email: -> input { Dry::Monads::Right(email: input[:email]) },
      }

      Inject = Dry::AutoInject(container: Container)
    end
  end

  it "support auto-injection of dependencies alongside step operations" do
    expect(transaction.("name" => "Jane", "email" => "jane@example.com").value).to eq(email: "jane@example.com")
  end
end

But right now, it doesn't:

  1) Using dry-auto_inject support auto-injection of dependencies alongside step operations
     Failure/Error: end.new
     ArgumentError:
       wrong number of arguments (given 1, expected 0)

I will try having a look at it! 💎

Has this issue been resolved? If no one's working on it at the moment, I'm happy to look into it.
