Description of problem:
From tripleo-ansble change log

* Mon Jun 03 2024 OSP Prod Chain <dev-null> 3.3.1-17.1.20240603220822.8debef3
- Replace EFI grub.cfg with a stub redirect (rhbz#2277685 rhbz#2278025)

This change could result in non-bootable system if /boot/grub2/grub.cfg is not valid.

Prior to this change, /boot/grub2/grub.cfg, is unused on efi systems.  While it generally should be good, there is no guarantee.

One specific example would be upgrade from rhel 7->8->9, where grub2 was changed from non-BLS to BLS config during rhel8 upgrade and the rhel7 /etc/grub2/grub.cfg was left intact.

Validating and if necessary creating /boot/grub2/grub.cfg should be done when adding the EFI stub redirect.
