Validation Error in FlinkSessionJob Savepoint UpgradeMode Configuration

When configuring a FlinkSessionJob to utilize the savepoint upgradeMode, the flink-kubernetes-webhook throws an exception indicating that the checkpoint/savepoint directory must be defined. This occurs despite having set the options state.checkpoints.dir and state.savepoints.dir in the flinkConfiguration of FlinkSessionJob. Interestingly, the validation passes only when these options are set in the flinkConfiguration of FlinkDeployment. However, I believe this behavior is flawed. The flinkConfiguration overrides from the FlinkSessionJob spec should also be considered during session job spec validation
