If items are orderable, show sort buttons
### Feature Description

### What is happening?

In `config.schema.json`, an array of items can be orderable:

```json
      "devices": {
        "title": "Accessories",
        "type": "array",
        "orderable": true,
        "uniqueItemProperties": [ "accessoryID" ],
        "items": {
          ...
        }
      }
```
`orderable` can be true(default) or false

That means that items can be dragged and rearranged.

The ordering above generates the following json config:

```json
                {
                    "accessoryID": "9304675",
                    "accessoryName": "Test Cron Secs",
                    "accessoryType": "sensor",
                    ...
                },
                {
                    "accessoryID": "8128246",
                    "accessoryName": "Stateful Timer Switch",
                    "accessoryType": "switch",
                    ...
                }
```

Dragging the "Stateful Timer Switch" accessory up one position reorders the accessories:

Clicking `Save` on the UI config popup, modifies the json config:

```json
                {
                    "accessoryID": "8128246",
                    "accessoryName": "Stateful Timer Switch",
                    "accessoryType": "switch",
                    ...
                },
                {
                    "accessoryID": "9304675",
                    "accessoryName": "Test Cron Secs",
                    "accessoryType": "sensor",
                    ...
                }
```

Other than each accessory showing a dropdown shadow, there is no indication that the items are orderable.

### What you expect to happen?

If items are orderable, [sorting buttons](https://jsonforms.io/docs/uischema/controls#sorting-buttons-showsortbuttons) would be displayed that show that the items can be reordered.

As `true` is the default for `orderable`, if there was a concern that the look and layout of plugins would change, maybe the sorting buttons would be displayed only if `orderable` was explicitly set to `true`.

### What problems would this new feature solve?

After creating multiple accessories, a user might decide that they would like to reorder them, maybe by grouping similar types (switches, lightbulbs) together.
