v12.1.0

• #1425 Update generated code

  • Add support for add_lines, remove_lines, and update_lines methods on resource Invoice

• #1420 Update static methods for delete/list on BankAccount/Card to throw NotImplementedError

  • The below methods have been throwing InvalidRequestError because the urls used to make the requests have been buggy. Updating them to throw NotImplementedError instead just like their counterparts for update & retrieve because they cannot be implemented without the parent id.

  Methods affected	Use these instead in the context of payment method	Use these in the context of external accounts
  Stripe:: BankAccount.delete	Stripe::Customer.delete_source	Stripe::Account.delete_external_account
  Stripe:: BankAccount.list	Stripe::Customer.list_sources	Stripe::Customer.list_external_accounts
  Stripe:: Card.delete	Stripe::Customer.delete_source	Stripe::Account.delete_external_account
  Stripe:: Card.list	Stripe::Customer.list_sources	Stripe::Customer.list_external_accounts

• #1427 Regenerate rbis
