ci: Handle reboot for transactional update systems

[HVSharma12]

Enhancement: - Added a block to identify and handle reboots for transactional update systems on package changes. Update README. Remove ALP-Dolomite var as it is no longer used.

Reason: Ensure necessary reboots are managed, as changes on transactional update systems are applied in a separate snapshot and require a reboot to take effect.

Result: Manages system reboots for transactional update systems when a package is installed.
