🐞 CDK: fix error when logging warning for types that could not be transformed

[pedroslopez]

What

The warnings recently introduced to the TypeTransformer in #16695 were causing an error to be thrown when the mismatched type was inside an array

Traceback (most recent call last):
  File "/airbyte/integration_code/main.py", line 13, in <module>
    launch(source, sys.argv[1:])
  File "/usr/local/lib/python3.9/site-packages/airbyte_cdk/entrypoint.py", line 123, in launch

  File "/usr/local/lib/python3.9/site-packages/airbyte_cdk/sources/abstract_source.py", line 316, in _as_airbyte_record
    transformer.transform(data, schema)  # type: ignore
  File "/usr/local/lib/python3.9/site-packages/airbyte_cdk/sources/utils/transform.py", line 189, in transform
    logger.warning(self.get_error_message(e))
  File "/usr/local/lib/python3.9/site-packages/airbyte_cdk/sources/utils/transform.py", line 193, in get_error_message
    key_path = "." + ".".join(e.path)
TypeError: sequence item 2: expected str instance, int found

This is beacuse e.path in this case was ['event_properties', 'items', 0].

How

Fix the issue by mapping all path parts to string
