What is your suggestion?

Given the irrelevance of 1.21 due to a hotfix short after, causing 1.21.1 as to be used instead, I kindly ask you to fix this mistake.

This affects both the CurseForge and Modrinth page

To be clear: 1.21 mods are still compatible even when used in a .1 instance
Tagging it correctly however ensures that various launchers, including Prism, are able to find said mod and download it without manually going out of your way to check and see whether or not Pehkui is even available for this version to begin with
