fix: various improvements on install.sh (#2724)

# What does this PR do?

Bulk improvements:

* The script has a better error reporting, when a command fails it will
print the logs of the failed command
* Better error handling using a trap to catch signal and perform proper
cleanup
* Cosmetic changes
* Added CI to test the image code against main
* Use the starter image and its latest tag
