fix: define mandatory_params as none in test_config_levels macro

The macro calls elementary.get_anomalies_test_configuration() with
mandatory_params but it was never defined in scope. In the original
dbt-data-reliability code, this was a parameter on the calling test
macros. Since test_config_levels doesn't need mandatory param validation,
define it locally as none.
