Request to add support for handling bytearray when outputting data in YAML format

[FumingZhang]

The current implementation of yaml formatter uses the safe_dump method, which does not support data of type bytearray, which leads to the following issue

File "/home/fumingzhang/aenv/lib/python3.12/site-packages/yaml/representer.py", line 58, in represent_data
node = self.yaml_representers[None](self, data)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/fumingzhang/aenv/lib/python3.12/site-packages/yaml/representer.py", line 231, in represent_undefined
raise RepresenterError("cannot represent an object", data)
yaml.representer.RepresenterError: ('cannot represent an object', bytearray(b'-----BEGIN CERTIFICATE-----\nxxxx\n-----END CERTIFICATE-----'))

def format_yaml(obj):
    import yaml
    try:
        return yaml.safe_dump(obj.result, default_flow_style=False, allow_unicode=True)
    except yaml.representer.RepresenterError:
        # yaml.safe_dump fails when obj.result is an OrderedDict. knack's --query implementation converts the result to an OrderedDict. https://github.com/microsoft/knack/blob/af674bfea793ff42ae31a381a21478bae4b71d7f/knack/query.py#L46. # pylint: disable=line-too-long
        return yaml.safe_dump(json.loads(json.dumps(obj.result)), default_flow_style=False, allow_unicode=True)
