Druid 25.0.0 creates a nested array rather than standard array when using string_to_array vs STRING_TO_MV

[acherla]

When applying string_to_array(Str, Delimiter) druid incorrectly converts the value to a nested array construct. This is different compared to STRING_TO_MV which properly transforms the delimited string value to a proper array. This is resulting in some array functions not working with array functions when using string_to_array.

Affected Version

25.0.0

Description

N/A not necessary

I think it's fixed already. I can't reproduce this on master. You can try once 26.0 is out.
