Opensearch v2.13.0 will not start with latest Graylog 2.3.8 helm chart

[mdacolo]

Describe the bug
When trying to upgrade to the latest version of Graylog and it's dependencies 6.0.4, mongodb 7.0.12-debian-12-r2, and opensearch 2.13.0 I ran into issues getting opensearch to start. Through some debugging I did find that opensearch 2.13.0 would deploy and start if one updated the dependency helm chart version to the opensearch latest of 2.21.0. I did not exhaustively test different helm chart version, just the 2.21.0. My request here is to update the dependecy helm chart version for at least openseaarch, but also mongodb (if deemed appropriate).

Version of Helm and Kubernetes:

Helm Version:

$ helm version
version.BuildInfo{Version:"v3.14.4", GitCommit:"81c902a123462fd4052bc5e9aa9c513c4c8fc142", GitTreeState:"clean", GoVersion:"go1.21.9"}

Kubernetes Version:

$ kubectl version
Client Version: v1.30.0
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.29.1

Which version of the chart:
3.8.0

What happened:
Opensearch failed to start, pod logs didn't have anything useful, nor did events to decipher what was wrong.

What you expected to happen:
Opensearch to start so Graylog would start

How to reproduce it (as minimally and precisely as possible):
Deploy Graylog with helm chart 3.8.0 and opensearch version 2.13.0. I also confirmed this behavior by deploying opensearch directly using the current helm chart version in Graylog helm chart of 2.8.0 and it failed to start, but it did start without issue with latest 2.21.0 opensearch helm chart version.
