Getting $ref history

In large schemas, understanding which $ref is being referenced when an error occurs can be helpful in debugging. We used to refer to the history of $ref with (ill-mannered) code like this:

for error in validator.iter_errors(instance):
    print(validator.resolver._scopes_stack)
    print(error)

However, with the current version of jsonschema, validator.resolver is deprecated, and it will be not possible to refer to it.

Is there a legitimate way to retrieve this information in jsonschema?

Reference: #1144

Start with the validator.iter_errors example in the issue and review reference #1144, then trace how the deprecated validator.resolver exposes the $ref scope history. Done means the project has a supported way to retrieve this debugging information without relying on the deprecated resolver, with the expected behavior documented or covered by tests.
