Helm test with ct install is installing as CronJob and not Deployment

[knelasevero]

While looking at #946 I noticed that in the gh-actions output https://github.com/kubernetes-sigs/descheduler/pull/945/checks ct install is installing descheduler in CronJob mode, which does not get useful events and logs back to us (even though we have helm-extra-set-args: "--set=kind=Deployment" set in https://github.com/kubernetes-sigs/descheduler/blob/master/.github/ci/ct.yaml) .

This worked at some point since we had this during reviews: #895 (review) 🤔

Installing it as Deployment will be better to check info and possibly add subsequent simple tests against that pod.

@knelasevero would you take a look at #953 and see if it makes sense?

Thanks @a7i ! And sorry for the delay on this one. For some reason I totally missed the notification

No worries @knelasevero
