ubuntu 24.04 key expired

I’m trying to install using the instructions here:
https://software.opensuse.org/download.html?project=graphics:darktable&package=darktable

I downloaded the key and it seems to be expired, so apt won’t add the repo:
$ gpg key.gpg
gpg: WARNING: no command supplied. Trying to guess what you mean …
pub rsa2048 2017-12-26 [SC] [expired: 2024-07-26]
3247B7519EDBEAB422E900A3040524A84C70D8B5
uid graphics:darktable OBS Project graphics:darktable@build.opensuse.org

Anyone else having this issue / who should I notify? Thanks!
