It looks like we never us Java's regex pattern with this - it's just a description string. In a follow up, can you rename this to, like description?

* Add Support for LIKE (LIST) (#129170) Adds support for LIKE function alternative syntax with a list of patterns. Examples: FROM foo | WHERE bar LIKE ("A*","B*", "C?") The new syntax is documented as part of the existing LIKE function documentation. We will use the existing WildcardLike java implementation for existing cases using the old syntax and one list argument case to improve mixed cluster compatibility.
