…ctorSearchAlgorithmConfi…" (#2531)

Reverts #2435

This PR caused a breaking change to the ACS memory store's
get_nearest_matches method

### Motivation and Context

This PR builds on #2435
- the previous PR updates azure-search to the latest package , where it
is recommended to use HnswVectorSearchAlgorithmConfiguration. The
previous implementation appears to be in a semi-deprecated state.

This new flow is the publicly recommended use for ACS according to
https://github.com/Azure/cognitive-search-vector-pr/tree/main/demo-python/code.

### Description
- update `azure-search-documents` dependency from `11.4.0b6 -> 11.4.0b8`
- index configuration changed from `VectorSearchAlgorithmConfiguration
-> HnswVectorSearchAlgorithmConfiguration`
- update `search_client.search()` call in `get_nearest_matches()` to be
consistent with the new index api
