Update view and config file to support latest @editorjs/list block

[musilondrej]

This pull request is in response to a change in the @editorjs/list block. The latest version of @editorjs/list generates data with a style parameter, as shown below:

{
    "id": "vQMrQPWD-O",
    "type": "list",
    "data": {
        "style": "unordered",
        "items": [
            "Item 1",
            "Item 2"
        ]
    }
}

To align with this new output format, the view and the config file have been updated to support the style parameter for list formatting.
