Subject: [PATCH] Add AutoComplete for semantic_text index_options, BBQ
 quantization (#226069)

Adds support for specifying `semantic_text` `index_options`:
<img width="581" alt="image"
src="https://github.com/user-attachments/assets/323148be-e456-45db-83a5-0f16e963fc16"
/>

And adds BBQ to the list of AutoComplete types:
<img width="583" alt="image"
src="https://github.com/user-attachments/assets/6c57bcb9-a3b2-4291-a005-1a464100d581"
/>

for both `semantic_text` and `dense_vector`.
