Format elyra existing functions to conform to new linting rules.
The new release of black v23 causes issues when linting elyra functions due to a new rule (removes empty line after function def) See example :

--- a/elyra/tests/metadata/test_metadata.py
+++ b/elyra/tests/metadata/test_metadata.py
@@ -49,7 +49,6 @@ os.environ["METADATA_TESTING"] = "1"  # Enable metadata-tests schemaspace
 
 # ########################## MetadataManager Tests ###########################
 def test_manager_add_invalid(tests_manager):
-
     with pytest.raises(ValueError):
         MetadataManager(schemaspace="invalid")
