Duplicate JMX exporter init container

Bug

Description

Describe the problem, what were you doing when you noticed the bug?

The JMX exporter init container seems to be duplicated in the Confluence STS causing it to hang.

create Pod confluence-0 in StatefulSet confluence failed error: Pod "confluence-0" is invalid: spec.initContainers[4].name: Duplicate value: "fetch-jmx-exporter"

I believe the duplication is here: https://repo1.dso.mil/big-bang/product/maintained/confluence/-/blob/main/chart/templates/statefulset.yaml?ref_type=heads#L130

And the original definition is here: https://repo1.dso.mil/big-bang/product/maintained/confluence/-/blob/main/chart/templates/statefulset.yaml?ref_type=heads#L61

Provide any steps possible used to reproduce the error (ideally in an isolated fashion).

Deploy Confluence with chart version 1.21.2-bb.0 or later.
