git_panel: Use specific label and prompt for reverting deleted file (#61554)

# Objective

I expected a different label for reverting a file deletion like Zed
already has for reverting a file creation.

## Solution

This PR implements a new label and prompt. VS Code also shows a
different prompt while keeping the label static but I think it makes
more sense to let both adapt.

## Testing

Just deleted a file and checked menu label and prompt.
