AWS Glue with Iceberg Source and Delta Target

I seem to keep getting a `version-hint.text` error when trying to use the .jar file to sync an existing iceberg table to a delta, using AWS Glue as my catalog. Im using the `my_config.yaml` file as directed in the doc's, but i feel like im missing something.

For instance:
```
sourceFormat: ICEBERG
targetFormats:
- DELTA
datasets:
-
# (i have this set to the parent path that holds the (metadata, data and _delta_log directories), ive tried other configurations as well. The _delta_log directory gets created, but nothing gets created in it, as i keep getting the error indicated above)
tableBasePath: s3://path
tableName: my_table
```

Do i need to create a catalog.yaml and clients.yaml file as well? I noticed these but i thought they were only for implementing custom sources other than Hudi, Iceberg or Delta.

If i do need to create these files, what would i set as the `catalogImpl: ` to for a source iceberg table that is managed by aws glue?
```
catalogImpl: io.my.CatalogImpl
catalogName: name
catalogOptions: # all other options are passed through in a map
key1: value1
key2: value2
```

Thanks in advance!

Start with the documentation and configuration examples for my_config.yaml, catalog.yaml, and clients.yaml, then investigate the reported version-hint.text error using the AWS Glue catalog and Iceberg-to-Delta setup shown. Done means establishing whether the configuration is supported and documenting or reproducing the required catalog settings and resulting behavior.
