WebClientResponseException.getResponseBodyAs throws exception instead of returning null for empty body

[kzander91]

Spring Framework: 6.0.11

The Javadoc of org.springframework.web.reactive.function.client.WebClientResponseException#getResponseBodyAs(java.lang.Class<E>) states:

spring-framework/spring-webflux/src/main/java/org/springframework/web/reactive/function/client/WebClientResponseException.java

Line 229 in 8404537

* @return the decoded content, or {@code null} if there is no content

However, when the response body is empty, the following exception is thrown: org.springframework.core.codec.DecodingException: JSON decoding error: No content to map due to end-of-input

Reproducer (extract and run the test):

I was expecting null, but I'm getting an exception instead.
