Currently, a validation results error produces output in a hard-to-understand dictionary: https://github.com/E3SM-Project/zppy/blob/main/zppy/__main__.py#L171

Suggestions for improving the error description:

• Pretty print the dictionary
• Print only the keys/values with False in the validation dictionary
• Print a link to the tutorial, which has examples of how values should look (but not for all parameters...)
• See if there's any way for the Validator to give more information on why it failed
