latest ghcup doesn't work on arch linux aarch64

Hi! i am running a arch linux container on my arm64 chromebook. ghcup worked fine till today afternoon, when i did a ghcup upgrade

now ghcup wont work at all because glibc 2_33 is not available.

i checked. the latest available glibc for archlinuxarm is version 2.32 which can be found here here

i don't think its necessarily a ghcup issue, but i don't know where else to file it? what do i do here?
