aws-for-fluent-bit auto_create_group option is always disabled for cloudwatchlogs plugin in fluentbit helm chart

**Describe the bug**

auto_create_group option is disabled, the pod reports this error below repeteadly, if I use cloudwatch intead of cloudwatchlogs plugin within the fluentbit helm values the log group is created, but that plugin has worst performance and has not templating options.

**Steps to reproduce**
Just enable cloudwatchlogs, i tested different image versions so i dont think the issue is in the image.

image:
repository: public.ecr.aws/aws-observability/aws-for-fluent-bit
tag: "2.28.5"
pullPolicy: IfNotPresent
…
cloudWatchLogs:
autoCreateGroup: true
enabled: true
match: "*"
region: "us-east-1"
logGroupTemplate: "/aws/eks/mycluster/$kubernetes['host'].$kubernetes['namespace_name']"
logStreamTemplate: "$kubernetes['pod_name'].$kubernetes['container_name']"
logRetentionDays: 14

**Expected outcome**

log group should be created , only old plugin cloudwatch does but not cloudwatchlogs

APPLICATION VERSION
2.31.12.20231011

* Chart name: aws-for-fluent-bit
* Chart version: 0.1.32
* Using EKS (yes/no), if so version? yes 1.29

Start with the aws-for-fluent-bit chart values shown in the issue and inspect the rendered configuration for the cloudwatchlogs plugin. Compare the autoCreateGroup setting with the emitted auto_create_group option, then reproduce with the provided values; done means the option is enabled and the missing log group is created.
