feat(space): add current key for Item

[VladislavNsk]

Опишите проблему

При использовании компонента Space, если удалить дочерний элемент, то все остальные элементы размонитруются и смонтируются заново, при условии что key никак не меняется при этом

Шаги для воспроизведения

Добавить в Space несколько элементов и после удалить первый

<Space>
  {rows.map(({text, id}) => (
      <Component key={id}>
        {text}
      </Component>        
  ))}
</Space>
<button>
 Удалить первую строку
</button>

Пример можно посмотреть тут

Ожидаемое поведение

Удалится первый элемент, остальные никак не среагируют на это
