BafS · web-flow · commit 89817110145f · 2022-08-24T10:12:15.000+02:00
* Fix jsonSerialize on PHP 8.1+

```
During inheritance of JsonSerializable: Uncaught ErrorException: Return type of FlixTech\SchemaRegistryApi\Schema\AvroReference::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice
```

* Use ReturnTypeWillChange to be PHP 7 compatible
