feat: add support for toggling enable_nested_fields in docsearch json

[drewzhao]

Change Summary

Typesense has supported since v24: https://typesense.org/docs/28.0/api/collections.html#notes-on-indexing-common-types-of-data

When using the typesense-docsearch-scraper , enabled_nested_fields is ignored.

This PR makes sure the "enabled_nested_fields" is read and effective when creating a collection.

Hi Team Could you please help review this PR?

When using llamaindex with typesense, a nested metadata field is required. Nested fields is already supported by typesense. I hope that I can leverage the existing typesense-docsearch-scraper when creating the nested fields.

Thanks.

I've published this in 0.12.0.rc12. Could you give it a shot and let me know how it goes?

@jasonbosco Tested with 0.12.0.rc12, it's working perfectly. 👍

The returned schema from "/collections/<collection_name>' contained the nested fields.

Here's an excerpt from my docsearch definition:

        { "name": "document_meta", "type": "object", "optional": true },
        { "name": "document_meta.section", "type": "string", "locale":"zh", "facet": true, "optional": true },
        { "name": "document_meta.difficulty_level", "type": "string", "facet": true, "optional": true },
        { "name": "document_meta.last_updated", "type": "string", "optional": true },
        { "name": "document_meta.author", "type": "string", "locale":"zh", "facet": true, "optional": true },
        { "name": "document_meta.category", "type": "string", "locale":"zh", "facet": true, "optional": true },
        { "name": "content_info", "type": "object", "optional": true },
