**Motivation**
Rollbacks appear in list views (such as history, recent changes), but also in the diff view. In both cases it should be possible to see a confirmation prompt
**User story**
As an editor for whom the rollback confirmation prompt is enabled
I want to see a rollback confirmation prompt when I click on "rollback X edits" in the diff view
so that I can revoke the action if it was not the one I intended.
**Mocks**
Before the user clicked on the rollback link:
{F28084805}
Once users who have the confirmation prompt enabled clicked on the link:
{F28084808}
**Acceptance Criteria**
[] If users with enabled rollback confirmation prompt click on `rollback X edits` in the header of the diff view, they see a confirmation prompt `Rollback of X edits? Rollback Cancel`
[] The confirmation prompt should appear in the same position the initial ` rollback X edits` had, with all possible syntax around it staying intact
[] If only one edit is supposed to be rollbacked, the wording should say `rollback 1 edit`
[] If users click on `Rollback` of the confirmation prompt, the rollback action should be executed
[] If users click on `Cancel`, the original state should be retained, i.e. ` rollback X edits` should again be visible
