[Bug] Google `.gemini` connector not recognized as valid connector id in elasticstack_kibana_action_connector

[phandox]

Describe the bug
Terraform can't spin up Gemini Connector for Elastic AI Assistant using elasticstack_kibana_action_connector resource.

To Reproduce
Steps to reproduce the behavior:
Assume that elastic connection is already set up and working

1. dummy terraform config

resource "google_service_account" "gemini_sa" {
  account_id = "ec-observability-ai-assist"
  project = "<redacted>"
}

resource "google_service_account_key" "observability_gemini" {
  service_account_id = google_service_account.gemini_sa.id
}

resource "google_project_iam_member" "observability_gemini" {
  member  = google_service_account.gemini_sa.member
  project = "<redacted>"
  role    = "roles/aiplatform.user"
}

resource "elasticstack_kibana_action_connector" "observability_gemini_connector" {
  provider = elasticstack.observability
  connector_type_id = ".gemini"
  name              = "gemini-playground"
  config = jsonencode({
    apiUrl = "https://europe-west3-aiplatform.googleapis.com"
    defaultModel = "gemini-1.5-pro-001"
    gcpProjectID = "<redacted>"
    gcpRegion = "europe-west3"
  })
  secrets = base64decode(google_service_account_key.gemini_sa.private_key)
}

2. terraform apply fails with

  # elasticstack_kibana_action_connector.observability_gemini_connector will be created
  + resource "elasticstack_kibana_action_connector" "observability_gemini_connector" {
      + config             = jsonencode(
            {
              + apiUrl       = "https://europe-west3-aiplatform.googleapis.com"
              + defaultModel = "gemini-1.5-pro-001"
              + gcpProjectID = "<redacted>"
              + gcpRegion    = "europe-west3"
            }
        )
      + connector_id       = (known after apply)
      + connector_type_id  = ".gemini"
      + id                 = (known after apply)
      + is_deprecated      = (known after apply)
      + is_missing_secrets = (known after apply)
      + is_preconfigured   = (known after apply)
      + name               = "gemini-playground"
      + secrets            = (sensitive value)
      + space_id           = "default"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes

elasticstack_kibana_action_connector.observability_gemini_connector: Creating...

Expected behavior
I would expect the connector to be created. I was able to make it work when I created it from UI

When I created connected in UI, I exported it as saved object and matched the config to Terraform. Thats how I find the .gemini as connector_type_id.

I'm encountering the same issue with AWS Bedrock:
