ci: Switch from AlmaLinux 8 to AlmaLinux 9

By the time of release, it's going to be more than two years
since AlmaLinux 9 was released and per our support policy,
AlmaLinux 8 (the previous major release) will be not supported.
Switch from AlmaLinux 8 to AlmaLinux 9.

This also means the website_job which depends on AlmaLinux 8
needs to be moved to newer AlmaLinux.
