[Live] Investigate resetting form values when underlying "data" is modified

[weaverryan]

Currently, if you trigger a live action where you perform an action that will change the form (e.g. you add a new "item" to a CollectionType), you do this by manipulating the underlying "form values": https://github.com/symfony/ux/blob/2.x/src/LiveComponent/src/LiveCollectionTrait.php#L42

It would be nice if you could modify the data on your underlying entity, and the have the form rebuild from there - e.g.

public function addTodoItem(): void
{
    // todoList would be the entity bound to the form
    $this->todoList->addItem(new TodoItem());

    // that's it: by modifying the underlying entity, the form will naturally render with an additional item
}
