azure-search-documents 12.1.0b1 no longer exports KnowledgeRetrievalReasoningEffort from azure.search.documents.indexes.models

[pamelafox]

Package Name
azure-search-documents

Package Version
12.1.0b1

Operating System
macOS

Python Version
3.14

Describe the bug
KnowledgeRetrievalReasoningEffort is no longer publicly importable from azure.search.documents.indexes.models in 12.1.0b1.

The preview KnowledgeBase docs still reference retrieval_reasoning_effort as using this type, but the symbol is not actually exported from the public models namespace.

To Reproduce

1. Install azure-search-documents==12.1.0b1
2. Run:

from azure.search.documents.indexes.models import KnowledgeRetrievalReasoningEffort
print(KnowledgeRetrievalReasoningEffort)

Expected behavior
KnowledgeRetrievalReasoningEffort should be publicly exported from azure.search.documents.indexes.models.

Actual behavior
The import fails.

Screenshots
N/A

Additional context
This creates a mismatch between the preview documentation and the actual public Python surface. If the intended pattern is now to pass string values directly, the docs should reflect that. Otherwise, the enum should be exported again.
