[ISSUE] Unable to delete databricks_sql_global_config resource configured with instance profile

[kr-arjun]

Configuration

# variable "databricks_connection_profile" {
  description = "The name of the Databricks connection profile to use."
  type = string
  default = "my-profile"
}

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.27"
    }

  databricks = {
    source = "databrickslabs/databricks"
    version = "~> 0.3"
    } 
  }
}

provider "aws" {
  profile = var.aws_connection_profile
  region = var.aws_region
}

provider "databricks" {
  profile = var.databricks_connection_profile
}

data "databricks_current_user" "me" {}

resource "databricks_sql_global_config" "this" {
  security_policy      = "DATA_ACCESS_CONTROL"
  instance_profile_arn = "arn:aws:iam::12345678:instance-profile/data-access-role"
  data_access_config = {
    "spark.sql.session.timeZone" : "UTC"
  }
}

Expected Behavior

The SQLendpoint global config should be deleted.

Actual Behavior

On trying to destroy databricks_sql_global_config resources, it fails with below error.

Error: cannot delete sql global config: Instance profile has invalid format. 
Example valid ARN: arn:aws:iam::1234567890:profile/name.

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply to create the sqlendpoint with sqlendpoint global config set
2. terraform destroy to destroy the sqlendpoints and sqlendpoint global configs.

Terraform and provider versions

Terraform v1.0.0
on darwin_amd64

• provider registry.terraform.io/databrickslabs/databricks v0.4.7
• provider registry.terraform.io/hashicorp/aws v3.74.0

Debug Output

It looks like the instance_profile_arn is set to empty string - should ideally be removed from API payload while deletion?
