WikiJS update script

[ChrisGoudt]

When I try to update the WikiJS LXC, I get this error:

`✓ Stopped Wikijs

• Updating Wikijs...cp: cannot stat '/opt/wiki/config.yml': No such file or directory
  ‼ ERROR 1@321 Unknown failure occurred.`

This seems to be caused by an incorrect path, in my installation, the correct path is /opt/wikijs/config.yml
