chore(updatecli) fix jenkinscontroller agents images manifests (delete unsued + fix existing

[dduportal]

Requires jenkins-infra/kubernetes-management#5923 to be deployed to have some AWS credential available.

As explained in #3739 (review), this PR should unblock #3739.

It is a fixup of #3737 which accidentally reintroduced an old updatecli manifest which was tracking all kinds of packer images for our agents but 2 years ago (so not only packer images for AMI and azure, but also non packer images).

This manifest is removed and the AMI tracking has been added for Linux (Ubuntu arm64 and Ubuntu x86).

Closes #3740 which was a result of the (now) removed manifest.

Local test and checks give the same result: the AMI ID for the 2 Ubuntu will be updated in an automatic PR once merged:
