Slimechunk expression wrong in 1.17

[Primorior]

Description

I used the slimeball expression to make it easier for my players to locate a slimechunk. While rightclicking with a slimeball it shows if there is a slimechunk or not. I attached the code.

Steps to Reproduce

-> Used this code as sk file:

on rightclick with slimeball:
	if chunk at player is a slime chunk:
		send "&aSlimechunk!"
	else:
		send "&cNo Slimechunk" 

-> Create world in 1.17 with seed "-8580642221070289223" (probably wrong with all seeds but in this one we used when one of my players found this issue)

-> Teleport to 178 / -2069

-> Use slime ball to see if it's a slimechunk and it says it is.
-> To validate if this is true, see here it's wrong, there is no slimechunk: https://www.chunkbase.com/apps/slime-finder#-8580642221070289223

CondIsSlimeChunk should use Chunk#isSlimeChunk if that method exists
