chore(updatecli): restore ubi9 manifest (RedHat Container Registry's json file is now valid)

[gounthar]

Status Update: UBI9 Manifest Rollback

We performed a rollback of the updatecli manifest for ubi9 due to parsing issues with RedHat's JSON file. The error can be viewed in the CI logs.

While the root cause remains unclear (possibly a transient error), the system is now functioning correctly.

Testing done

updatecli diff --debug \
    --config ./updatecli/updatecli.d/rhel-ubi9.yaml \
    --values ./updatecli/values.github-action.yaml 2>&1
