Update README.md for aql example

[jandvorak-sol60279]

added "type" key for aql example for aql results to work correctly with from_aql method for ArtifactoryPath

if "type" isnt included in aql response dict(s) it will raise ArtifactoryException and thus example isnt working

    def from_aql(self, result):
        """
        Convert raw AQL result to pathlib object
        :param result: ONE raw result
        :return:
        """
        result_type = result.get("type")
        if result_type not in ("file", "folder"):
            raise ArtifactoryException(
                f"Path object with type '{result_type}' doesn't support. File or folder only"
            )
