IRC does not support creating V1 table via snapshot procedure (stage create)

[puchengy]

Apache Iceberg version

1.5.2

Query engine

Spark

Please describe the bug 🐞

CatalogHandlers (used by Rest Catalog) when executing updateTable with transaction code will always create an empty builder of default table version 2 (in Iceberg 1.5.2). This does not work if user intentionally want to create v1 table, as a result, query like

CALL spark_catalog.system.snapshot(..., map('format-version', '1');

will fail with Cannot downgrade v2 table to v1 error.

A propose fix is when calling TableMetadata.buildFromEmpty() we honor the format version if the request already set it.

I believe this was fixed by 24d26b6, which was released with 1.6.0
