[Public Catalog] Display the Documentation details for packs under the "Data source" tab

[rudouglas]

Description

Once the Data source tab is added to a pack as part of #1511 , if any new documentation info is available populate that data in the tab. This data should come from the config.yml e.g.:

documentation:
  - name: AWS RDS installation docs
    description: This is the description
    url: https://docs.newrelic.com/docs/integrations/amazon-integrations/aws-integrations-list/aws-rds-monitoring-integration

This should be a Tile component showing the

• name parameter as title of the tile
• description field as other content in the tile
• Link to the url when clicked.

In future packs may have multiple references to documentation, so ensure that we account for this when displaying content in the tab.

NOTE: the design image shows this tile under Overview tab, but it should be under Data sources

Acceptance Criteria

• [x] Populate the Data sources tab with the documentation reference defined in the pack.
• [x] Support multiple documentation links for packs with many doc references.

@jpvajda We display a sort of "category" for each component at the bottom of the tile.

Do we want to add a "documentation" category to it? This is actually a comment for https://github.com/newrelic/newrelic-observability-packs/issues/135

Blocked on the documentation field getting stitched in

This has been merged into our feature branch. We're still missing some copy at the top of this tab, but we can tackle that when we receive that content (added to the production readiness list).
