SpringBoot Upgrade to Spring Framework 6.0.5

Comment From: wilkinsona

This upgrade needs a little more attention as it causes three failures in ConfigurationPropertiesBeanRegistrationAotProcessorTests due to the now-prohibited use of an instance supplier callback.

This seems to have been closed accidentally as the version for the Spring Framework is still pointing to 6.0.5-SNAPSHOT.

See https://github.com/spring-projects/spring-boot/blob/3.0.x/spring-boot-project/spring-boot-dependencies/build.gradle#L1358
