Rule validation does not show in errors when the key validated is in an array of hashes

Describe the bug

Rule validation does not show in errors when the key validated is in an array of hashes

To Reproduce

Provide detailed steps to reproduce, an executable script would be best.

1. Define the contract

#address_contract.rb
class AddressContract < Dry::Validation::Contract
  json do
    required(:street_address).filled(:string)
    required(:country).filled(:string)
  end
end

2. define another contract that uses AddressContract

#new_user_contract.rb
class NewUserContract < Dry::Validation::Contract
  json do
    required(:user_details).array(:hash) do
      required(:email).filled(:string)
      required(:address).hash(AddressContract.schema)
    end
  end

  rule(:user_details).each do
    unless /\A[\w+\-.]+@[a-z\d\-]+(\.[a-z\d\-]+)*\.[a-z]+\z/i.match?(value[:email])
      key.failure('has invalid format')
    end
  end
end

3. Create the contract

contract = NewUserContract.new

4. Validate the following payload

payload = {
   user_details: [{email: 'jane', address: '17'}]
 }
 
 contract.call(payload)

Expected behavior

expected output

> #<Dry::Validation::Result{:user_details=>[{:email=>"jane", :address=>"17"}]} errors={:user_details=>{0=>{:email=>["has invalid format"], :addresss=>["must be a hash"]}}}>

but got

> #<Dry::Validation::Result{:user_details=>[{:email=>"jane", :address=>"17"}]} errors={:user_details=>{0=>{:address=>["must be a hash"]}}}>

As you can see, it is missing the rule validation for the format of the email. Is this a bug? Or am I missing something here?
