Insufficient error information provided when yaml_resolver.py has a JSON schema error

[james-ball-qualcomm]

Had a long debug session with Derek because JSON schema checker doesn't provide sufficient information on a failure. Need to find a better way to show the error information than using "best_match()".

Here's the current error message:

JSON Schema Validation Error for certificate_model/MC200-64.yaml:
'certificate_model/MC200-32.yaml#' is not of type 'array'

Here's the code:

write_yaml(resolved_path, resolved_obj)
if do_checks and ("$schema" in resolved_obj):
  schema = _get_schema(resolved_obj["$schema"])
  try:
    schema.validate(instance=resolved_obj)
  except ValidationError as e:
    print(f"JSON Schema Validation Error for {rel_path}:")
    **print(best_match(schema.iter_errors(resolved_obj)).message)**
    exit(1)
