Missing latest gson

When updating our code to springboot 3.4.0 out pipeline using the **mcr.microsoft.com/azure-functions/java:4-java21** image stopped working. This is due to there being a new dependency in springboot on gson 2.11.0. Packaging this version with the application does not help since it is also included in the jar file used in the docker container. It is seen first and then there is a problem loading classes that does not exist. I tried just now also with the nightly build of the container and that did not work either. Not sure how the process is here but it would be nice to get new build of the java container with the latest gson in it.

Start with the mcr.microsoft.com/azure-functions/java:4-java21 image definition and its build inputs, then check how dependencies in the container's JAR are assembled. Reproduce the Spring Boot 3.4.0 packaging failure and verify that a rebuilt image includes gson 2.11.0 without the class-loading conflict.
