Clarification: IntRangeList and IntRangeExpr

## Description

Range lists (IntRangeList) have a limit of 1024 items. Range expressions (IntRangeExpr) generate a list of items but are not subject to the same 1024 item limit. For clarity, it'd help to explicitly note that lists generated from IntRangeExpr types are not subject to the 1024 item limit.
