Add Security Analytics sample data to Dashboards

[Jon-AtAWS]

Currently we have this set of sample data:

Can we add a security analytics data set, along with the associated saved objects (if we need any apart from what the SA plugin provides out-of-the-box). That will make it easy for users to experiment with the plugin and its features.

@opensearch-project/admin could we transfer to the security analytics plugin repo team to prepare the data and tests? Dashboards team could help if they need.

@Jon-AtAWS , Thank you for the suggestion, great idea. As we add more features on Security Analytics, providing the various capabilities on a sample set of data allows users to explore and create detectors, findings and alerts.
