While trying to set up Wireguard interface and its peers, I had a question in my mind that can we remove peers, other than just disabling it? After executing `delete interfaces wireguard wg0 peer Example`, everything seemed fine until commiting and saving which returned error.
The error contained these: `cmd 'wg set wg0 peer ['ebFx/1G0ti8tvuZd94sEIosAZZIznX+dBAKG/8DFm0I='] remove'` and `Key is not the correct length or format: '[ebFx/1G0ti8tvuZd94sEIosAZZIznX+dBAKG/8DFm0I=]'`. There is also a stack trace corresponding to this:
```File "/usr/libexec/vyos/conf_mode/interfaces-wireguard.py", line 117, in <module>

As a person who is also interested in coding, I have checked out [here](https://github.com/vyos/vyos-1x/blob/d1f6b8a8a9e3298b10fe6a04f4edb531582efc88/src/conf_mode/interfaces-wireguard.py#L64) and have seen that `peer_config` variable is list. Hence, during command formatting process, it is formatted in a wrong way. One easy solution can be taking first and only element of the array (since one peer can only have one pubkey) [at this line](https://github.com/vyos/vyos-1x/blob/d1f6b8a8a9e3298b10fe6a04f4edb531582efc88/src/conf_mode/interfaces-wireguard.py#L65).
