Hint how to fix `cannot import name 'SomeDataSet'` in Kedro >= 0.19

[yury-fedotov]

Context

In both my company's internal slack and the Kedro slack, I'm frequently seeing a question like:

Getting an error like this, anyone encountered before?
ImportError: cannot import name 'ExcelDataSet' from 'kedro_datasets.pandas'

Which is resolved by changing ExcelDataSet to ExcelDataset.

Feature

I'm wondering if Kedro could provide a custom error message with a hint that since 0.19, Dataset is spelled with lowecase s?

Possible implementation

When dataset definitions from Kedro catalog get parsed to paths of Python objects, do something like:

for dataset in catalog:
    if dataset.type.endswith("Set") and dataset.type.startswith("kedro_datasets")
        raise ValueError(
            "Since Kedro 0.19, Dataset is spelled with lowercase 's'. Got {dataset.type}"
        )
