Review Comment:
Nit: can do a switch on content to get either DELETE_SCAN_COLUMNS or
SCAN_COLUMNS to make it clearer.

Review Comment:
I think there's actually a bug here, and it only checks latest spec for
Unpartitioned. if we have partition fields before but removed them, we will
not show them. See other metadata tables like BaseFilesTable.schema.
Anyway its unrelated, but made https://github.com/apache/iceberg/issues/7533
to track it.
