fix: centos7 -> roskylinux 8

Summary

CentOS 7 reached its end-of-life on 30/06/2024, making its repositories unavailable. Therefore, continuing to build CI images for it is no longer sensible. We have now switched to Rocky Linux 8.

Так как это коммит в ядро, то лучше добавить в сообщение коммита описание, почему это изменение было сделано (и да, это не fix, а ci). Например:

ci: Centos 7 EOL

CentOS 7 reached its end-of-life on 30/06/2024, making its
repositories unavailable. Therefore, continuing to build CI
images for it is no longer sensible. We have now switched to
