Feature request

Which Delta project/connector is this regarding?

• [x] Spark
• [ ] Standalone
• [ ] Flink
• [ ] Kernel
• [ ] Other (fill in here)

Overview

UniForm now supports both Hudi and Iceberg. But the comment in UniversalFormat.scala is outdated, only mentioning support to Iceberg. These comment in UniversalFormat.scala should be updated to describe the UniForm support to Hudi.

Example comments from the file:

Currently, UniForm only supports Iceberg. When `delta.universalFormat.enabledFormats` contains"iceberg", we say that Universal Format (Iceberg) is enabled.
