wsl --unregister <Distro> should warn users that their data will be permanently deleted.

@benhillis is already working on this.

Since Apr 9, 2023.

### Windows Version

Microsoft Windows [Version 10.0.22621.1413]

### WSL Version

1.1.6.0

### Are you using WSL 1 or WSL 2?

- [X] WSL 2
- [ ] WSL 1

### Kernel Version

5.15.90.1

### Distro Version

Ubuntu 20.04

### Other Software

_No response_

### Repro Steps

wsl --unregister

### Expected Behavior

After running the command line, the program should ask the user to answer yes or no regarding the permanent removal of the distribution.

Example:
```
wsl --unregister
Are you sure you want to permanently delete ? (yes/no)
```

This will prevent more users from mistakenly deleting all their information as it has been reported on multiple occasions.

For automation purposes, an extra flag should be added to skip the message (e.g., --force).

Example:
```
wsl --unregister --force
```

### Actual Behavior

No warnings are prompt to the user. WSL 2 deletes the distribution without asking the user.
