konflux: update the mirrors file to take 1.12 builds into account

[littlejawa]

Fixes: KATA-5167

NOTE: this is actually needed on the 1.12 branch, but having both mirrors mentioned here will help for testing (no need to choose which mirror file to use).
I will pick this on the branch after it's merged, so that the Konflux automation running there can find and use this mirror.

📝 Walkthrough

Walkthrough

This PR extends the image mirror set configuration by adding -v1-12 destination image mirror entries for OSC components. Both the tag-based and digest-based mirror sections are updated with parallel entries for images such as osc-monitor, osc-caa, osc-operator, and others, enabling mirroring of versioned image variants alongside the existing base mirror entries.

✅ Passed checks (14 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately summarizes the main change: updating the mirrors file to support 1.12 builds, which is confirmed by the raw summary showing additions of '-v1-12' destination image mirror entries.
Description check	✅ Passed	The description is directly related to the changeset, explaining why the mirrors file was updated (to support 1.12 builds) and providing context about the backport plan and associated Jira ticket.
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	PR modifies only .tekton/images-mirror-set.yaml (YAML config), with no changes to test files or Ginkgo test definitions, making the test name stability check inapplicable.
Test Structure And Quality	✅ Passed	PR adds YAML and supporting files. Test code follows quality guidelines: single-responsibility tests, proper BeforeEach/AfterEach, meaningful assertion messages, and codebase consistency.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	PR modifies only .tekton/images-mirror-set.yaml, a YAML configuration file; no Ginkgo e2e tests are added, so SNO test compatibility check does not apply.
Topology-Aware Scheduling Compatibility	✅ Passed	PR only modifies .tekton/images-mirror-set.yaml (image mirror configuration), not deployment, operator, or controller files. No scheduling constraints introduced.
Ote Binary Stdout Contract	✅ Passed	This is a Kubernetes operator project, not an OTE test binary. The OTE Binary Stdout Contract check applies only to test binaries; this runs as a cluster controller manager.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR only modifies .tekton/images-mirror-set.yaml (Tekton configuration), not test files. No Ginkgo e2e tests are added, so IPv6/disconnected network check does not apply.
No-Weak-Crypto	✅ Passed	YAML configuration file for image mirrors contains no weak cryptography (MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB), custom crypto implementations, or secret comparisons.
Container-Privileges	✅ Passed	File contains only image mirror registry mappings with no container/pod definitions or privilege escalation markers (privileged, hostPID/Network/IPC, SYS_ADMIN, allowPrivilegeEscalation).
No-Sensitive-Data-In-Logs	✅ Passed	The PR modifies only .tekton/images-mirror-set.yaml with container registry mirror configurations. No logging code, passwords, tokens, API keys, PII, or sensitive data are present in the changes.
