On some Rocky Linux 9 deployments, we are seeing GRUB defaulting to the
old kernel included in the DIB image, even after newer kernels have been
installed. This appears to be related to the presence of Boot Loader
Specification (BLS) entries with a machine ID lower in alphabetical
order than the current one:
[stack@host ~]$ sudo cat /etc/machine-id
cd3361a338fe47348de9937e51a7a4aa
[stack@host ~]$ sudo ls -l /boot/loader/entries/
total 20

Add a new `reset-bls-entries.yml` playbook which will rename existing
BLS entries using the current machine ID. This should prompt Grub to
pick the most recent kernel on next reboot.
