Swap print() call in dataset.py with logger.info()

[timothyas]

Hi folks! First off, many thanks for this amazing resource. I have created a workflow for comparing forecast models directly against observations, and I've found the nnja-ai datasets and API to be incredibly useful. Hats off to you all 👏

This PR is just a micro suggestion, so let me know what you think. Right now, every time a dataset gets loaded we get a print statement like:

Loading manifest for dataset '{self.name}'

Is there any reason this is a print statement? When I run this for example using SLURM, it results in these print statements coming at the end of the job and in a different location from the rest of the nnja_ai logging, since they're not piped in the same way as the logger. Because of that, the statements are not really useful progress markers. I think it would be nice to get these with the rest of the logs, hence the PR.

Let me know what you think! Thanks again for this awesome package!
