(CAT-2416) Address almalinux 8 provisioning issues

[LukasAud]

Following an investigation on recent Almalinux 8 provisioning failures, it was found that there is a security policy issue that prevents ubuntu 24.04 runners from running the provisioning script for Almalinux
8. This commits defaults Almalinux 8 provisioning to always run on ubuntu 22.04 runners.

Checklist

• 🟢 Spec tests.
• Manually verified.
