Update almalinux-deploy.sh

[natenasby]

Changed code in subscription_manager_unregister() to correctly unregister the RHEL subscription on both RHEL 9 and RHEL 10, removing a blocker for migrating from RHEL 10 -> AlmaLinux 10.

Tested on RHEL 9 and RHEL 10 VMs. Since the tool targets EL8/EL9 conversions per the documentation, I haven’t yet validated this on RHEL 8 but am happy to do so if you’d like.

Thank you for reporting the issue. I can confirm it exists on RHEL 10, and it doesn't on RHEL 8 and 9.
