feat: can disable typesense prefix

[Barbapapazes]

Hello 👋,

Typesense offers semantic search capabilities using embeddings. However, the prefix search option is not compatible with vector (embedding-based) search. This PR enables users to set the prefix option to false when performing a vector search.

Relevant documentation: https://typesense.org/docs/29.0/api/search.html#query-parameters:~:text=Indicates%20that%20the,for%20all%20fields).

Current error when using vector search with prefix set to true:

Prefix search is not supported for remote embedders. Please set `prefix=false` as an additional search parameter to disable prefix searching.

Can't directly approve of changes here, but it looks right

I was wondering why the parameters array couldn't be merged with the one in the configuration to avoid to add manually every parameters from typesense while being future proof?
