Replace RFC 7807 by RFC 9457 in property documentation

[ghusta]

Documentation for property spring.mvc.problemdetails.enabled should be updated with RFC 9457.

It would reflect the changes already done in Spring FWK :

• https://github.com/spring-projects/spring-framework/commit/89ce63f1f36c2e526ea5270fb7a5b969043d7554
• https://github.com/spring-projects/spring-framework/issues/32806

See for example in :

• https://github.com/spring-projects/spring-boot/blob/v3.3.1/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/reactive/WebFluxProperties.java
• https://github.com/spring-projects/spring-boot/blob/v3.3.1/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/servlet/WebMvcProperties.java
