Fix return type of some list expressions

[TPGamesNL]

Description

Fixes the return type of some list expressions: ExprSortedList, ExprShuffledList, ExprReversedList.

All 3 loops in this code don't parse without this PR (with error loop-value is not a text):

command /test:
	trigger:
		set {_l::*} to 5 times
		loop reversed indices of {_l::*}:
			set {_i} to (loop-value) parsed as integer
			message "%loop-value% ; %{_i}%"
		loop shuffled indices of {_l::*}:
			set {_i} to (loop-value) parsed as integer
			message "%loop-value% ; %{_i}%"
		loop sorted indices of {_l::*}:
			set {_i} to (loop-value) parsed as integer
			message "%loop-value% ; %{_i}%"
