GH-324: Annotate @CircuitBreaker with @AliasFor

Fixes #324

Using the annotation `@CircuitBreaker` with Spring Framework 6 leads to the following warning:

```
 WARN org.springframework.core.annotation.AnnotationTypeMapping [main] : Support for convention-based annotation attribute overrides is deprecated and will be removed in Spring Framework 6.1. Please annotate the following attributes in @org.springframework.retry.annotation.CircuitBreaker with appropriate @AliasFor declarations: [include, maxAttempts, noRetryFor, maxAttemptsExpression, notRecoverable, exclude, exceptionExpression, label, retryFor]
```

* Provide a respective fix for `@CircuitBreaker` annotation.
* Deprecated attributes which are deprecated already in the `@Retriable`
