Subject: [PATCH] [@types/blessed] Allow additional properties for `IOptions`
 interface (#40547)

* [@types/blessed] Allow additional properties for `IOptions` interface

This change allows for arbitrary properties to be stored
onto the options object of `Node` instances. This is useful
for extra metadata to be stored onto a node and is accessible
on the `node.options` property.

For example, the `blessed-css` module utilizes the additional
properties `id` and `className` for matching CSS selectors:

```typescript
const bg = blessed.box({
    parent: screen,
    id: 'bg'
});
```

* Add test

* Add to authors
