Fix SageMaker Unified Studio trigger hook config

[weiyu1029]

Description

Forward region_name, verify, and botocore_config from
SageMakerUnifiedStudioNotebookOperator to
SageMakerUnifiedStudioNotebookTrigger when execution is deferred.

Previously, these AWS hook configuration values were not forwarded to the
trigger. As a result, the triggerer could construct its hook using different
AWS configuration from the operator that originally started the notebook run,
including potentially polling a different AWS region.

This change ensures that the deferred trigger receives and serializes the same
AWS hook configuration used by the operator.

Closes #72279

Tests

Extended the deferrable operator unit test to verify that:

• region_name survives trigger serialization.
• verify survives trigger serialization.
• botocore_config survives trigger serialization.
• The derived waiter_max_attempts behavior remains unchanged.

Just one nit. Approved pending green CI.

I would add the issue number to the PR description as well i.e. #72279
