The yum-minimal element was configuring C, en_US, and en_US.UTF-8 as languages to be installed by packages notably leaving out C.UTF-8. This appears to be due to CentOS 7 not supporting C.UTF-8 (its glibc was too old). Since then CentOS 8, CentOS 8 Stream, and CentOS 9 Stream all reportedly support C.UTF-8. Since we don't support CentOS 7 any longer it should be safe to update yum-minimal to include C.UTF-8. This ensures we have modern C locales available for use which are starting to be expected (for example Ansible apparently wants a UTF8 locale and some hardcode it to use C.UTF-8).
