Event name is not the same through the tutorial

[Wafa2kameel]

submitItem event should be submit in https://ng-girls.gitbook.io/todo-list-tutorial/more-workshops/crud_http/get

And that to make it consistent with the the first part of the tutorial:
https://ng-girls.gitbook.io/todo-list-tutorial/workshop-todo-list/add-items

<div class="todo-app">
  <app-input-button-unit (submitItem)="addItem($event)"></app-input-button-unit>

  <ul *ngIf="todoList | async as todoItems">
    <li *ngFor="let todoItem of todoItems">
      <app-todo-item [item]="todoItem"
                     (remove)="removeItem($event)"
                     (update)="updateItem($event.item, $event.changes)"></app-todo-item>
    </li>
  </ul>
</div>
