typesense_collection does not support auto schema

[jon-flowers]

Typesense allows you to use an auto-detected schema (see https://typesense.org/docs/0.22.2/api/collections.html#with-auto-schema-detection)

With this Terraform provider, you can create a collection with an auto schema fairly easily, using something like the code below

resource "typesense_collection" "test_collection" {
  name = "test_collection"

  fields {
    name = ".*"
    type = "auto"
    optional = true
  }
}

This will create fine. However, once you start populating documents into Typesense, the schema will add fields. When this happens, future Terraform applies will result in the new fields being called out as needing to be removed, and the whole collection will be replaced. This causes all documents to get deleted. Example, where the new documents had a single location field that was added to the schema:

  # typesense_collection.test_collection must be replaced
-/+ resource "typesense_collection" "test_collection" {
      ~ id            = "test_collection" -> (known after apply)
        name          = "test_collection"
      ~ num_documents = 14 -> (known after apply)

      ~ fields {
          ~ facet    = false -> (known after apply)
            index    = true
            name     = ".*"
            optional = true
            type     = "auto"
        }
      - fields {
          - facet    = false -> null
          - index    = true -> null
          - name     = "location" -> null
          - optional = true -> null
          - type     = "string" -> null # forces replacement
        }

I noticed this because I was creating the collection with the auto schema, and then creating the typesense_sync document that backfilled the data. On the next apply, which should have had no changes, it indicated my collection would need to be replaced. The backfill will then not occur again until you update or replace the sync document, in which case the process starts over.

Is there a way to do this so that auto schema will work with this Terraform provider? Or will only a pre-defined schema work as expected?
