Restore confirmation differs between groups and projects
## Problem
When restoring a group or project that is pending deletion, the restore confirmation message is slightly different between the two. We should make sure they are aligned.
### Restore confirmation for projects

### Restore confirmation for groups

## Proposal
- [ ] Align wording between group and project restore confirmation

## Implementation guide
1. Update text in [/ee/app/controllers/ee/projects_controller.rb#L33](https://gitlab.com/gitlab-org/gitlab/blob/8ce6e5f772542fde3b9c3310c27b12a7dd76eb39/ee/app/controllers/ee/projects_controller.rb#L33) to match above proposal
