I expect there are tests to be updated, either in test/io/core or test/data_catalog.py (not sure where). Can you check with this?

I couldn't find any other references to kedro.extras... or kedro[...DataSet] in the codebase; test/io/test_data_cataog.py and tests/framework/cli/test_catalog.py already import from kedro_datasets as per #3057

@AhdraMeraliQB You are right! I was looking at the main branch accidentally, looks good to me then!
