Components syntax with Phlex::Kit

[cirdes]

With Phlex::Kit, we can create components without using "render" and "new". This approach will make the components look much better and improve the developer experience.

I was discussing this with @joeldrapper on this PR, and my suggestion is to aim for this syntax:

PhlexUI::Accordion do |accordion|
  accordion.item do
    accordion.trigger do
      div do
        p { "What is PhlexUI?" }
      end
    end
  
    accordion.content do
      p { "PhlexUI is a UI component library for Ruby devs who want to build better, faster." }
    end
  end
end

instead of:

render PhlexUI::Accordion.new do
  render PhlexUI::Accordion::Item.new do
    render PhlexUI::Accordion::Trigger.new do
      div do
        p { "What is PhlexUI?" }
      end
    end
  
     render PhlexUI::Content.new do
      p { "PhlexUI is a UI component library for Ruby devs who want to build better, faster." }
    end
  end
end

I will be able to open PRs to support Phlex::Kit for all the current components if we decide to proceed
