While you can set a default value for the Link extensions class attribute using
```javascript
Link.configure({
HTMLAttributes: {
class: 'my-custom-class',
},
})
```
It is currently not possible to dynamically set the class attribute when calling setLink() e.g.
```javascript
this.editor.chain().focus().extendMarkRange('link').setLink({href: url, class: 'this class should be added'}).run();
```
This change allows for that by default, without needing to extend the Link extension.
