schema_change_handling required for sap_hana_db service but not supported

[fivetran-justinbeausoleil]

Describe the bug
With version 1.2.8, the resource fivetran_conector_schema_config requires schema_change_handling. However, the service sap_hana_db does not support schema_change_handling, and fails during apply.

To Reproduce

resource "fivetran_connector_schema_config" "sap_hana_db_schema_config" {
  count = local.dev_only # only create a dev environment

  connector_id           = fivetran_connector.sap_hana_db[count.index].id
  schema_change_handling = "ALLOW_ALL"
  schemas = {
    "SAPABAP1" = {
      "enabled" : true,
      "tables" : {
        "BSEG" : {
          "enabled" : true
        }
      }
    }
  }
  validation_level = "NONE"
}

Expected behavior
Because sap_hana_db does not support schema_change_handling, the key/value pair should not be required for the indicated service.

Logs & Output
