feat: shows a confirmation dialog on question deletion

[Koc]

We've found that sometimes users can accidentally delete their questions. Let's add confirmation dialog to be more consistent with other deletions.

Just a question: how could you accidentally delete a question? The action is already hidden in the question menu, so you have to actively open the menu and then click on the button. I don't think that we should over complicate our UI and have too many pop up dialogs.

Google doesn't show a confirmation when you delete a question, same for Microsoft. Both already show the delete button directly on the question and not even inside a menu.
