Dataset 'lighteval/MATH' doesn't exist on the Hub or cannot be accessed.

Hi, thanks for your wonderful work!

When I tried to use the following code, it throws error (datasets.exceptions.DatasetNotFoundError: Dataset 'lighteval/MATH' doesn't exist on the Hub or cannot be accessed):

from dspy.datasets import MATH
dataset = MATH(subset='algebra')

It seems that the download link is no longer valid and therefore a pontential fix is needed.
Thanks a lot!

It seems like the dataset was actually taken down. It's not immediately clear to me what the context is.

We might actually have to do the tutorial with a different dataset...

Found the context here: huggingface/lighteval#494 (comment). Seems like the original dataset violated some copyright restriction, and was taken done.

There is a replacement thought: https://huggingface.co/datasets/DigitalLearningGmbH/MATH-lighteval, let me make a PR to point to the replacement.
