Spring Security Add custom ServerHttpHeadersWriter to HeadersSpec

Summary

We should add the ability to have a custom ServerHttpHeadersWriter to HeaderSpec.

@Bean
SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
    http
        // ...
        .headers(headers ->
            headers
                .writer(serverHttpHeadersWriter)
        );
    return http.build();
}
