Missing "consumer group" in the Event Hub configuration causes internal server error during configuration

Good day team.
It seems that the connector requires a "consumer group" to be attached to the Event Hub.
If such configuration is missing, an internal server error is generated at the "save" step of the connector wizard.

Please review https://jira.corp.adobe.com/browse/PLATIR-41376 for details.

Expected actions: please include an explicit requirement for the "consumer group" in the documentation.

Issue in ./help/sources/connectors/cloud-storage/eventhub.md

Open help/sources/connectors/cloud-storage/eventhub.md and review the Event Hub configuration requirements. Confirm the documentation explicitly states that a consumer group is required, including its relevance before saving the connector configuration. Done means the requirement is clear to users and the documented setup prevents the reported configuration failure.
