azure.search.documents.knowledgebases.models.KnowledgeBaseRetrievalRequest exposes max_output_documents in docs, but nothing on documentation

### Type of issue

Code doesn't work

### Description

Trying to query an Az AI Search KnowledgeBase, using **max_output_documents** parameter (see attached image). It doesn't work, responses are restricted to 8 items in output list.

Further, this option and a host of other options from this screenshot are not even visible in documentation at: [KnowledgeBaseRetrievalRequest Class](https://learn.microsoft.com/en-us/python/api/azure-search-documents/azure.search.documents.knowledgebases.models.knowledgebaseretrievalrequest?view=azure-python)

We are using

Start with the KnowledgeBaseRetrievalRequest documentation page and its content source, docs-ref-autogen/azure-search-documents/azure.search.documents.knowledgebases.models.KnowledgeBaseRetrievalRequest.yml. Compare the documented properties with azure-search-documents 12.1.0b1, focusing on max_output_documents and the other options shown in the report. Done means the available request options are accurately exposed in the generated documentation and the reported eight-item behavior is clarified.
