remove column airbyte_data in airbyte

Currently, there is no built-in functionality in Airbyte to exclude system fields such as

_airbyte_data

from the output. These fields are added by Airbyte for data synchronization and tracking purposes. However, you can create a transformation step after the extraction to remove these fields. This would involve creating a new table without these fields and copying the data over. Please note that this operation should be done with caution as these fields contain important information for data synchronization. For more details, you can refer to this [discussion](https://github.com/airbytehq/airbyte/discussions/34526) on the Airbyte GitHub page.
