[FEATURE]Add Getting-Started Tab in the integration dialog

[YANG-DB]

Is your feature request related to a problem?
Today as part of the getting started campaign we would like to be able to see the getting started process for each integration as part of the integration dialog itself.

What solution would you like?
The following assets have been added to the catalog content

• getting-started schema json field
• getting-started.md markdown document in the getting-started folder of the integration
• getting-started-1.0.0.ndjson asset containing the markdown document in the form of a dashboard

  "getting-started": {
    "ingestion": ["otel-collector","data-prepper"],
    "structured": "true",
    "technology": "OpenTelemetry",
    "protocol": ["otel"],
    "info": "https://github.com/opensearch-project/opensearch-catalog/tree/main/integrations/observability/otel-services/info/Tutorial.md",
    "live-sample": "true",
    "workflows": [
      {

We would like to add a tab containing the getting-started markdown rendered as a dialog to show the steps needed for using this integration.

Selecting the Getting-Started button would produce the content of the getting-started markdown :
