vtoyboot breaks sd-encrypt hook

In the file `/etc/mkinitcpio.conf`:

Before running vtoyboot, I have:

```
HOOKS=(base systemd autodetect microcode modconf kms keyboard sd-vconsole block sd-encrypt filesystems fsck)
```

After running vtoyboot, it becomes:

```
HOOKS=(base systemd autodetect microcode modconf kms keyboard sd-vconsole block sd- ventoy encrypt filesystems fsck)
```
