OCPBUGS-115309: Re-enable sandboxed-containers extension for 5.0

[aaradhak]

KATA-4726 made kata-containers available again for RHCOS 9.8 and 10.2. Restore the sandboxed-containers extension in those definitions so 5.0 builds can ship it.

prow/images failure seems to happening in all PRs , it doesnt seem to be related to the changes done here -

@aaradhak Is the build issue already being tracked?
This PR as you know is a blocker for 5.0 and important for kata containers
I hit the same failure trying to build a cluster with this PR: https://prow.ci.openshift.org/view/gs/test-platform-results/logs/release-openshift-origin-installer-launch-azure-modern/2095864325007740928
We'd like to test kata with 5.0 and would be great to have this merged soon.
