        Create a new validator like this one, but with given changes.

        Preserves all other attributes, so can be used to e.g. create a
        validator with a different schema but with the same :kw:`$ref`
        resolution behavior.

        >>> validator = Draft202012Validator({})

        The returned object satisfies the validator protocol, but may not
        be of the same concrete class! In particular this occurs
        when a :kw:`$ref` occurs to a schema with a different
        :kw:`$schema` than this one (i.e. for a different draft).

        ...     schema={"$schema": Draft7Validator.META_SCHEMA["$id"]}
        ... )
