This PR adds comprehensive support for creating and managing Auth0 Event Streams in the Terraform provider. It introduces both a resource and data source for event streams, supporting two destination types: EventBridge and Webhook configurations.

Key changes include:

• New auth0_event_stream resource for creating, updating, and managing event streams
• New auth0_event_stream data source for retrieving existing event streams by ID
• Support for both EventBridge and Webhook destination types with proper validation
