feat(datahub-sync): adds DataPlatformInstance aspect

[sgomezvillamor]

Change Logs

This update introduces the ability to set DataPlatformInstance via configuration.

Before this PR:

• DataPlatformInstance was not emitted for either Dataset or Container entities.
• It was automatically injected by the DataHub backend, only for Dataset, and included only the platform field.

With this PR:

• If no platform instance is configured:

  • DataPlatformInstance is consistently emitted for both Dataset and Container entities, including only the platform field.

• If a platform instance is configured:

  • DataPlatformInstance is consistently emitted for both Dataset and Container entities, including both the platform and instance fields.
  • The platform instance is included in the browse paths.
  • The platform instance is also included in the identity (URN) for both Dataset and Container.

Consistent and correct management of DataPlatformInstance aspect is relevant for the platform instance filtering in the DataHub UI as well as the browsing experience.
