Data_sources documentation outdated, should mention Amazon S3 and Prometheus [DOC]

[AntonEliatra]

Current documentation for data_sources: https://opensearch.org/docs/latest/dashboards/management/data-sources/#create-a-data-source-connection is outdated. Currently there are only 2 options to connect via OpenSearch Dashboards, which is Amazon S3 and Prometheus.

• Request a change to existing documentation
• Add new documentation
• Report a technical problem with the documentation
• Other

The documentation should be updated with new screenshot and mention the 2 available options for configuring data_sources with GUI.

*Version: 2.15
