Allow submitter users to accept/ignore suggestions

Description

There were initially two different button groups: for admin users and the other for non-admin users (which was allowing non-admin users only to undo an action).

Now, when the topic is marked as WITHDRAWN or REINSTATED, we display only the button group containing a delete button for submitter users. Conversely, for other topics, submitter users will see all three buttons. Although the button group remains the same for admin and non-admin users, the delete button's functionality varies. For non-admin users, it acts as 'UNDO' action (as it was in the previous behavior for non admin users) and for the administrator it will be a 'REJECTED’ action.
