Corrected AuthenticationEventPublisher Type

[ximinghui]

The AuthenticationEventPublisher interface does not provide the setAdditionalExceptionMappings(Map<Class<? extends AuthenticationException) method, and it is located in the DefaultAuthenticationEventPublisher implementation class.

Since Spring Security 6.3.3 uses Java 17, the variable type declaration can also be changed to the var keyword available since Java 10+. However, I don’t see the var keyword used in the documentation, so I continue to use traditional type declarations to maintain consistency in the code style.

Thanks, @ximinghui! You are correct that Spring Security does not use var. That is because we try and align ourselves with Spring Framework's style guide.
