Right doesnt' work as expected

SELECT right(s, 3) FROM test_str_right
Expected only Comet native operators, but found Project.
plan:  Project [COMET: Substring pos and len must be literals]
+- CometNativeColumnarToRow
   +- CometNativeScan parquet spark_catalog.default.test_str_right

This is a main case and it shouldn't fallback
