In the grub2 element the grub2-efi-x64-modules package is missing in the centos 9 section, this cause a failure because grub2 cannot find the neccecary files when installing the bootloader on EFI systems. It seems grub2-efi-x64-modules was not included in release 9, this is likely why the block was added initially without this package. Since it is now there, the Centos 9 specific block is no longer needed. Removing the rhel 8 block as well, as it is identical to the family "redhat" block i.e it is redundant.

grub2
This image installs grub2 bootloader on the image, that's necessary for the local boot feature in Ironic to work. This is being made a separated element because usually images have grub2 removed for space reasons and also because they are going to boot from network (PXE boot).
