fix - Add default schema name to S3 archive metadata

[GtheSheep]

Closes same issue as Pipeline fails if archive enabled with s3 and tap table name is not in format <<schema_name>>__<

>

Proposed changes

Add a default schema_name to the S3 metadata, also happy to just set this to an empty string if you prefer? or perform in the metadata function itself
