Description
Running OpenSearch 2.x clusters and adding them, causes it to add an alert about EOL status. This isn't correct as OpenSearch is based on 7.x.

Steps To Reproduce
List the steps to reproduce your problem:

1. Open elasticvue
2. Add an OpenSearch cluster

Opensearch is currently not officially supported by elasticvue (even though it mostly works). There might be more work to do - i will track that in this issue. Possible things to implement:

• JWT based access (see [FEAT] plan to support oidc #206)
• Snapshot S3 settings (see [BUG] - Add S3 Repository for AWS missing role_arn option #209 )
