Security notice

OpenSearch Dashboards was upgraded to 2.17.1 which mitigates CVE-2024-45801

What does this PR do / why do we need this PR?

Upgrades OpenSearch to Chart Version 2.26.1 and OpenSearch Dashboards to Chart Version 2.24.1, which upgrades the App Version to 2.17.1. This mitigates CVE-2024-45801, which the current version of dompurify used in OpenSearch Dashboards is affected by. It also adds a fix for the "red screen" bug present for newer versions of Google Chrome. This PR also changes the name of the index that OpenSearch Dashboards uses to store saved objects (Visualizations e.t.c..) back to the default .kibana, as this name override was causing issues with System Index permissions, preventing access from all regular users including admin and OpenSearch Dashboards. Changing this back to the default value also fixes the Reporting feature in OpenSearch Dashboards which has not been functional previously.

Ensure that the migration only performs the specialised steps if we have a version diff on OpenSearch.
Else it should do a generic apply to ensure that is still is up to date in terms of config.
