[BUG] `Noticed::DeliveryMethods::Email` does not support keyword arguments

[tcannonfodder]

Bug Report

Describe the Bug:

ActionMailers that use keyword arguments in their methods are not able to be used in Noticed because there is not support for keyword arguments.

Example mailer:

class User::EmergencyPasskeyRegistrationMailer < ApplicationMailer

  def emergency_registration_request(emergency_passkey_registration:)
    user = emergency_passkey_registration.user
    token = emergency_passkey_registration.generate_token_for(:emergency_registration)
# ...

To Reproduce:

1. Step 1
2. Step 2
3. ...

Expected Behavior:
These mailers should work, since keyword arguments are a common Ruby feature

Possible Fix:

I've got the following override from a patched subclass I made, submitting as a PR shortly.

def deliver
    mailer = fetch_constant(:mailer)
    email = evaluate_option(:method)
    args = evaluate_option(:args) || []
    kwargs = evaluate_option(:kwargs) || {}

    mailer_instance = mailer.with(params)

    if kwargs.present?
      mail = mailer_instance.public_send(email, **kwargs)
    else
      mail = mailer_instance.public_send(email, *args)
    end
    (!!evaluate_option(:enqueue)) ? mail.deliver_later : mail.deliver_now
  end
