Bug: Undefined constant "SCOPE_USER_INFO"

[siemendev]

Hi folks,
I think there is a minor mistake in this bundle:

In Nitrado.php line 78:
  Undefined constant "ItsMeStevieG\OAuth2\Client\Provider\SCOPE_USER_INFO"  

this (\ItsMeStevieG\OAuth2\Client\Provider\Nitrado::getDefaultScopes)

protected function getDefaultScopes(): array
{
    return [SCOPE_USER_INFO];
}

should probably be

protected function getDefaultScopes(): array
{
    return [self::SCOPE_USER_INFO];
}
