Works in tandem with `<ModalLayer />` to render modals. First of all ensure
you have a modal layer on the page (it doesn't have to be in the same
template)

```hbs
<ModalLayer />
```

Then all modals will be rendered into the `<ModalLayer />` for example:

```hbs preview-template
<ModalDialog
  @onclose={{noop}}
  @onopen={{noop}}
  @aria={{hash
    label="Screenread name of the modal"
  }}
as |modal|>

  <!-- Save a reference to the modal component so we can call its methods -->
  {{did-insert (set this 'modal' modal)}}

  <BlockSlot @name="header">
    <h2>
      Modal Header
    </h2>
  </BlockSlot>
  <BlockSlot @name="body">
    <p>
      Modal body
    </p>
  </BlockSlot>
  <BlockSlot @name="actions">
    <button type="button"
      {{on "click" modal.close}}
    >
      Close modal
    </button>
  </BlockSlot>
</ModalDialog>

<button
  type="button"
  {{on 'click' (optional this.modal.open)}}
>
  Open Modal
</button>

```
