fix double splat bug

ActiveRecord::Base.transaction expects a hash, but the lib using
single splat.

With Ruby 3 or above, this caused errors such as:

ArgumentError:
  wrong number of arguments (given 1, expected 0)
  # gems/3.0.0/gems/activerecord-6.1.7.6/lib/active_record/transactions.rb:208:in `transaction'
  # gems/3.0.0/gems/transaction_retry-1.0.3/lib/transaction_retry/active_record/base.rb:32:in `transaction_with_retry'
