OCPBUGS-96722:bump containerd to fix CVE-2026-53488

[jechen0648]

Summary

• Add containerd to the explicit INSTALL_PKGS list in the Dockerfile so the image is rebuilt with the patched RPM that fixes CVE-2026-53488.
• The containerd package is present in the network-tools-rhel9 image via the ocp/5.0:tools base image but was not previously pinned explicitly. Listing it here ensures yum installs the latest available version (>= 1.7.33 / 2.x fixed releases) at build time.
• The vulnerability allows host-root command execution via unvalidated image config labels in the CRI plugin.

Resolves: OCPBUGS-96722

Test plan

• Verify image builds successfully with containerd installed at a fixed version (>= 1.7.33 or >= 2.0.10/2.1.9/2.2.5/2.3.2)
• Confirm CVE scan on the rebuilt image no longer flags CVE-2026-53488

Check name	Status	Explanation
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	Only Dockerfile changed; no Ginkgo tests or test titles were added or edited, so the stable-name check is not applicable.
Test Structure And Quality	✅ Passed	Only Dockerfile changed; no Ginkgo test code or test patterns were introduced, so the test-structure check is not applicable.
Microshift Test Compatibility	✅ Passed	Only Dockerfile changed; no Ginkgo/e2e tests were added or modified, so there’s nothing MicroShift-specific to validate.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	Only Dockerfile changed; no new Ginkgo e2e tests were added, so SNO multi-node compatibility is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	Only the Dockerfile package list changed to add containerd; no manifests, controllers, replicas, affinity, node selectors, or topology logic were modified.
Ote Binary Stdout Contract	✅ Passed	Only Dockerfile changed; no process-level code or stdout writes were modified, so the OTE stdout contract is unaffected.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	Only Dockerfile changed; no new Ginkgo e2e tests were added, so IPv6/disconnected compatibility concerns are not applicable.
No-Weak-Crypto	✅ Passed	Diff only adds containerd to Dockerfile; no weak-crypto, custom crypto, or secret-comparison code is introduced.
Container-Privileges	✅ Passed	The PR only adds containerd to Dockerfile INSTALL_PKGS; no privileged, hostPID/network/IPC, SYS_ADMIN, root, or allowPrivilegeEscalation settings were added.
No-Sensitive-Data-In-Logs	✅ Passed	Only Dockerfile package list changed; no logging code or sensitive-data exposure was added.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title accurately summarizes the Dockerfile change to add containerd for the CVE fix.
