More descriptive Error messages

[dvsrepo]

Is your feature request related to a problem? Please describe. I'd like to have more descriptive error codes and messages. Right now we return message and error codes directly from the Server, and I think we should have more fine-grained error message.

As an example, this happens when you try to retrieve a dataset that doesn't exist (or cannot be found) using rg.load from the client:

NotFoundApiError: Argilla server returned an error with http status: 404
Error details: [{'code': 'argilla.api.errors::EntityNotFoundError', 'params': {'name': 'ner_descriptions_with_terms', 'type': 'ServiceDataset'}}]

Complete error trace:

In this case, the dataset existed but was not in the default namespace.
