Docs: Add clear indicators for required fields in Spark syntax on CREATE TABLE.

[bitsondatadev]

Is there a way to set a table column as an identifier field and required field using Spark DDL? I’m not seeing anything here … https://iceberg.apache.org/docs/latest/spark-ddl/ … which I assume means that I would need to use the Iceberg lib directly?

This same question came up in OSS slack recently. There are no docs on the "not null" spark syntax for making a column required in the Spark docs or the iceberg docs.
