Issue Summary

Bitbucket bundles OpenSearch 2.19.1 in Bitbucket 9

However, Bitbucket's Plan your Upgrade page shows a warning, "Your current search server won't be supported" when bundled OpenSearch is used.

I was able to reproduce the same 9.4 and 9.6 versions 

Steps to Reproduce

1. Install Bitbucket 9.6.3.
2. Go to Administration -> Plan your upgrade, where you will see the warning.\

Expected Results

Bitbucket 9 Bundles Opensearch Version 2.19.1 which is supported so there should not be any WARNING

Actual Results

There is a warning:

Workaround

Currently there is no known workaround for this behaviour. A workaround will be added here when available
