bug(terraform): false positive for SQLDatabaseSSLDisabled in google terraform provider >=6.0.1

[henrythor]

Expected Behavior

A google_sql_database_instance with settings.ip_configuration[].ssl_mode set to "TRUSTED_CLIENT_CERTIFICATE_REQUIRED" or "ENCRYPTED_ONLY" should be a negative. settings.ip_configuration[].require_ssl is deprecated and removed from provider as of version 6.0.1.

Actual Behavior

kics is looking for deprecated attribute settings.ip_configuration[].require_ssl and returning a false positive in its absence

Steps to Reproduce the Problem

Use the following file

resource "google_sql_database_instance" "psql" {
  name             = "test-psql-database"
  region           = "europe-west1"
  database_version = "POSTGRES_15"
  project          = "my-project"

  settings {
    activation_policy = "ALWAYS"
    availability_type = "REGIONAL"
    disk_autoresize   = true

    ip_configuration {
      ipv4_enabled                                  = false
      private_network                               = var.vpc_id
      enable_private_path_for_google_cloud_services = true
      ssl_mode                                      = "TRUSTED_CLIENT_CERTIFICATE_REQUIRED"
    }
    backup_configuration {
      binary_log_enabled             = var.binary_log_enabled
      enabled                        = var.backup_enabled
      location                       = var.region
      point_in_time_recovery_enabled = var.point_in_time_recovery_enabled
      start_time                     = var.backup_start_time
      transaction_log_retention_days = var.transaction_log_retention_days

      backup_retention_settings {
        retained_backups = var.retained_backups
      }
    }
  }
}

Run the following command:

docker run -t -v $PWD:/path checkmarx/kics:latest scan -p /path -o "/path/"

Get the following output:
