Update php-qrcode and php-settings-container for PHP 8.1

By running the following command after updating composer.json

```
composer update chillerlan/php-qrcode chillerlan/php-settings-container
```

This change fixes a deprecation warning from Preferences ->
Personal data / Authentication -> Authenticator (OTP).

```
Return type of chillerlan\Settings\SettingsContainerAbstract::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice

The issue is fixed in php-settings-container 2.1.1 [1] Here I use the
latest php-qrcode version for another PHP 8.1 fix [2].
