Conversion of Athena Engine created Iceberg Table in AWS Glue as catalog source fails

### Please describe the bug 🐞

Hi, I am trying to convert an Iceberg table created using Athena Engine in AWS Glue catalog to Delta format. This is to enable catalog federation in to Unity catalog without copying the actual data files.
The error seems to suggest that the GLUE catalog as source for Iceberg still uses Hadoop approach of identifying the latest version pointer. IT seems to look for version-hint, but in in this case the version pointer is managed by glue catalog and metadata file naming convention is 00000-uuid-metadata.json and not v0.metadata.json.
The error, YAML file and python code to run the Xtable command is provided below.

**It failed with error**

### Code of Conduct

- [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct)

Start by reproducing the supplied athena_sync.yaml and Python invocation with RunCatalogSync. Read IcebergTableManager.java, especially getTable, along with IcebergConversionSource.java and the HadoopTables stack trace to understand how the GLUE source is loaded. Done means the Athena-created Iceberg table converts to the configured DELTA target without NoSuchTableException.
