Add support for inertiaui/modal

[skryukov]

InertiaRailsContrib provides support for InertiaUI Modal in the Rails application.

With InertiaUI Modal, you can easily open any route in a Modal or Slideover without having to change anything about your existing routes or controllers.

By default, InertiaUI Modal doesn't require anything from the Inertia Server Adapters, since it just opens modals without changing the URL.
However, InertiaUI Modal also supports updating the URL when opening a modal (see the docs on why you might want that: https://inertiaui.com/inertia-modal/docs/base-route-url).

Setup

1. Follow the NPM installation instructions from the InertiaUI Modal documentation.

2. Enable InertiaUI Modal, turn on the enable_inertia_ui_modal option in the inertia_rails_contrib.rb initializer:

InertiaRailsContrib.configure do |config|
  config.enable_inertia_ui_modal = true
end

This will add a new render method inertia_modal that can be used in the controller actions:

class PostsController < ApplicationController
  def new
    render inertia_modal: 'Post/New', props: { post: Post.new }, base_url: posts_path
  end
end

TODO:

• Implement the inertia_modal renderer
• Add patch to support redirect back
• Add tests
• Write a cookbook article
