[I] Glue: schemasToGlueColumns reorders columns by field ID [iceberg-go]
badalprasadsingh opened a new issue, #1562:
URL: https://github.com/apache/iceberg-go/issues/1562
### Apache Iceberg version
main (development)
### Please describe the bug 🐞
When syncing an iceberg schema to a Glue table, `schemasToGlueColumns` collects columns into a Go map and sorts them by Iceberg Field ID. This produces a physical Glue column order that differs from the table's current logical schema order whenever columns have been _reordered_, _dropped_, or _added_ out of ID sequence.
We should not be tampering with the order of the columns. The current schema's logical column order should be preserved, then append the historical columns, with **no sorting**. A behavior which is similar to [Iceberg-Java](https://github.com/apache/iceberg/blob/60975ecd8d9352cfe62448dd59915b7d7bd57011/aws/src/main/java/org/apache/iceberg/aws/glue/IcebergToGlueConverter.java#L346-L366).
