docs: fix documentation to refer to anemoi datasets instead of zarr datasets

[floriankrb]

Description

Refering to Zarr outside of the anemoi-datasets package breaks the encapsulation principle.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

Issue Number

Code Compatibility

• I have performed a self-review of my code

Code Performance and Testing

• I have added tests that prove my fix is effective or that my feature works
• I ran the complete Pytest test suite locally, and they pass
• I have tested the changes on a single GPU
• I have tested the changes on multiple GPUs / multi-node setups
• I have run the Benchmark Profiler against the old version of the code
• If the new feature introduces modifications at the config level, I have made sure to update Pydantic Schemas and default configs accordingly

Dependencies

• I have ensured that the code is still pip-installable after the changes and runs
• I have tested that new dependencies themselves are pip-installable.
• I have not introduced new dependencies in the inference portion of the pipeline

Documentation

• My code follows the style guidelines of this project
• I have updated the documentation and docstrings to reflect the changes
• I have added comments to my code, particularly in hard-to-understand areas

It may be worth renaming the ZarrDatasetNodes class to AnemoiDatasetNodes in the near future, but this will break all the configs

@JPXKQX so it's that something you'd prefer to wait to fix it because it would be more breaking changes? Cause if so, at least we could have an issue opened to capture that

I have no preference, but in agreement with Florian PR, I just realised that it is not the correct name. All anemoi datasets are zarr datasets, but not vice versa, and we only support anemoi datasets in this node builder.
